The research into fiber laser technology has been fueled by numerous advantages that fiber lasers provide, as well as their superiority to bulk solid-state lasers; fiber lasers have not only motivated scientific study but have attracted significant commercial interest.

The benefits of fiber laser systems include the following:

  1. Efficient heat dissipation;

The unique geometry of fiber laser medium allows for efficient heat dissipation due to a ratio of surface area to the active volume being large. This benefits laser power scaling and makes thermal management easily attainable.

  1. Excellent output beam quality;

Due to the confinement of laser radiation in the fiber waveguide structure, fiber laser beam quality is high.

  1. Compactness and ruggedness;

All-fiberized structure design of fiber lasers eliminates the need for complicated alignment of free-space optical components, thus resulting in a simplified laser architecture.

  1. Reduced mode distortion;

Thermally induced mode distortion is often observed in traditional solid-state lasers; fiber lasers have a possibility to significantly reduce mode distortion by a specific physical design of the fiber.

The performance of fiber laser systems has been improving over the past 50 years due to significant scientific interest. The development of fiber materials, drawing technology fiber component fabrication, etc. have led to an improvement of fiber lasers in several areas. Emission wavelength selection has been broadened and now includes a wide variety of lasers, from ultraviolet fiber lasers to mid-infrared lasers.

Fiber lasers for cutting and drilling applications: femtosecond fiber lasers, picosecond fiber lasers

on December 12, 2017

Fiber lasers for cutting and drilling applications: femtosecond fiber lasers, picosecond fiber lasersMultimode fiber lasers have been used in concrete drilling and cutting. The reason behind the use of fiber laser system in this application is the ability of fiber lasers to cut concrete without fracturing it. The concrete structures that are designed to be earthquake-proof often contain things like rebar to bolster its strength so it won’t just crumble if an earthquake hits. Conventional drilling techniques are not gentle enough for concrete structures. This is where fiber laser cutting systems are used.

Fiber laser systems are already used in other cutting and drilling applications; for example, Q-switched fiber lasers are used in pulsed materials working, such as laser marking or working semiconductor electronics, as well as for LIDAR.

There is a significant interest in smaller fiber lasers for micro-and nanoscale machining. For fiber lasers that have a short enough pulse duration, shorter than about 35 ps, no material splatter occurs during cutting or drilling, just ablation, eliminating the formation of kerfs and other unwanted artifacts on the metal being cut. Femtosecond fiber lasers are able to cut materials without heating the surrounding area, allowing material work without damaging or weakening the surrounding area. Moreover, holes can be cut with high aspect ratios, e.g. drilling rapidly drilling small holes through 1-mm-thick stainless.

Femtosecond fiber lasers have been found to be extremely useful in a variety of applications that deal with transparent materials. They are widely used in LASIK eye surgery, where femtosecond fiber lasers are used to cut flaps by being focused tightly with a high-numerical-aperture lens onto a spot below the eye’s surface, causing no damage at the surface, but a breakdown of the eye material at a controlled depth. Due to this, the cornea – an area of the eye that is crucial for vision – remains unharmed. Femtosecond fiber lasers, along with picosecond fiber lasers are used in a variety of other medical applications, some of which include shallow-penetration surgery in dermatology, and use in certain kinds of optical coherence tomography (OCT).

There are many other areas of femtosecond fiber laser and picosecond fiber laser applications besides drilling and cutting. Scientific applications of femtosecond fiber lasers include laser-induced breakdown spectroscopy, time-resolved fluorescence spectroscopy, and general materials research.

Sub-micron spatial imaging resolution can be achieved through the use of optical microscopy which offers well-established techniques. The development of fiber optic technology, including fiber laser systems, has been noticed and used in many applications. Recently, researchers have found that ultrashort light pulses that are produced by femtosecond fiber lasers can be utilized in a variety of new biomedical imaging modalities. There are several techniques that utilize the high peak power that is possible with ultrashort pulses. The pulses can be focused to high intensity to drive nonlinear-optical processes, e.g. multiphoton absorption in molecules used as fluorescent labels.

Some biologically-important substances, like lipids, nucleic acids, sugars, etc. have characteristic vibrational spectra which can be distinguished easily. The generation of images with chemical contrast is possible through the use of microscopy with vibrational spectroscopy. The imaging is a basis of coherent Raman scattering (CRS) microscopies – it allows to detect the presence of certain substances without the use of exogenous dyes.

The development of femtosecond fiber lasers has been a big step in achieving new advances in nonlinear microscopy. Femtosecond fiber lasers have enabled dramatic growth of multiphoton and harmonic-generation imaging. This can be explained by various benefits that fiber lasers offer:

  1. The waveguide medium eliminates the need for precise alignment and makes long cavity length possible;
  2. Fiber lasers offer high beam quality, which is extremely valuable for many areas of fiber laser applications;
  3. Fiber gain media are efficient and can adequate levels of power for bioimaging;
  4. Fiber lasers are naturally suitable for integration with endoscopic instruments.

Fiber lasers for deep metal etching

on November 14, 2017

Deep etching in metal is vital for numerous applications, some of which include oil and gas exploration, gun and fire arms manufacturing, aerospace, pipe lines, infrastructure projects where metal is used, etc. In most of these applications, the etching metal parts are marked to depth exceeding 0.254 mm. This depth is justified by the need of the serial number, date of manufacture, part number to be hard to remove without the metal part breaking. The printed information needs to survive time, elements like water, heat and cold, oil and gas leaks, collapse of a bridge, etc.

Fiber lasers are considered to be the fastest, easiest, least expensive and most beneficial way of deep metal engraving for most industrial applications. The deep metal etching is achieved with high power fiber lasers that are able to cut deeper into the metal at faster speeds. The latest developments of fiber optic technology allow fiber lasers to be controlled during operation, which provides opportunities for wobble features.

There are numerous advantages of fiber laser deep metal etching:

  • The use of fiber lasers for metal etching reduces metal fatigue;
  • The requirements regarding depth and permanence of metal parts identification are easily complied;
  • The costs of deep metal etching are reduced;
  • Fiber laser deep metal etching is eco-friendly.

For the past several decades, CO2 lasers and YAG lasers have been used in laser cutting, etching and engraving applications. However, these lasers are being actively replaced by fiber laser systems as they perform much better at a lower cost. Their rising popularity is explained by their better working parameters, high energy efficiency, fault tolerance and durability. Fiber lasers are currently used in many laser welding, cutting and engraving applications and will soon replace all CO2 laser systems.

Fiber laser system for solar sail: potential for a breakthrough

on October 31, 2017

Fiber laser system for solar sail: potential for a breakthroughThe prospect of interstellar travel has been a dream of humanity for a long time. The recent rapid technological advances made interstellar travel a possibility, providing possible solutions for the difficulties that come with travelling between stars or planetary systems, such as large distances, power supply limitations, etc. One of the biggest limitations for interstellar travel is the fuel source. Long distances between stars make the fuel storage and efficient use of fuel a difficult problem for spacecraft manufacturers and developers. A solar sail, a form of spacecraft propulsion  using radiation pressure exerted by sunlight, is a promising way of providing propulsion for interstellar travel.

The further the spacecraft travels from the Solar System, the less intense the sunlight becomes, gradually making the solar sail obsolete. To resolve this issue laser beam powered propulsion has been proposed: the giant sails are pushed by lasers or masers to a significant fraction of the speed of light.

At the moment, researchers have already deployed several solar sails in space. In theory, an advanced solar sail could reach around 13% of the speed of light, as well as being able to withstand a wide range of temperatures, perform a gravitational slingshot move around the sun. Solar sails are ultra-thin, light and durable, which makes them ideal for interstellar travel. However, laser propelled solar sail is expected to reach about 25% of the speed of light. The array of lasers are planned to be installed on Earth and fire continuously at the sail for several minutes, which will propel the spacecraft to 60,000 kilometers per second.

The leading researchers and investors in the field of laser-powered solar sail design and construction are waiting for the breakthroughs in the laser industry, including fiber laser systems that are the most promising technology among other laser systems. The 100-gigawatt array of lasers is around a million times more powerful than today’s biggest continuous lasers, that put out several hundreds of kilowatts. The array may be composed of several lower powered lasers, however, they will need to be finely tuned and brought into phase with each other in order for the light waves produced by lasers to add and not cancel each other out. This technology has not been developed yet and requires the most work from laser manufacturers.

The solar sail itself must be worked on, as the material that can be potentially used in its construction needs to be extremely durable in order to withstand the powerful acceleration caused by the laser array for several minutes. The materials that have been tested so far are able to withstand such high forces for less than a second.

The projects that utilize solar sails plan to complete the technology and launch satellites and spacecrafts in the next 20 years, which does force fiber laser manufacturers under pressure to develop the needed technology. In turn, researchers in the field of space technologies need to be on the lookout for new and developing companies that offer promising solutions for laser-powered solar sails.

Fiber laser cutting vs CO2 laser cutting

on October 24, 2017

The difference between fiber laser and CO2 laser performance has caused a confusion in the marketplace as the pros and cons of two technologies. The comparison of the two technologies can present the advantages and disadvantages of both technologies and reveal the potential of their use for laser cutting.
The light inside a fiber laser system is created by banks of diodes. The optic cable is used to amplify and channel the light. This process is similar to data transfer where fiber optic technology is widely used. The light that exits the fiber cable, is focused by a lens onto the material that needs to be cut.
Fiber laser systems for laser cutting are superior to CO2 lasers as the production of light is 200% more efficient than via a traditional CO2 laser, as the delivery of light is much simpler and does not require expensive optical mirrors. Fiber lasers are able to perform at high speeds and provide high cutting efficiency due to their inherent design. Other benefits of fiber laser systems for laser cutting include:
no moving parts or mirrors, unlike CO2 laser, which reduces maintenance requirements and operating costs;
much higher electrical efficiency, which also results in lower running costs;
fiber lasers are able to cut these materials more efficiently than CO2 lasers, namely, they are three times quicker in a straight line cutting off 1 mm mild;
fiber laser systems are able to cut reflective materials without damaging the backing material.
The main disadvantages of CO2 lasers mainly relate to their cutting speed during the processing of thin materials; however, the cutting speed of CO2 lasers exceeds that of fiber lasers when processing thicker materials. In thick materials, typically above 5 mm, CO2 lasers have higher laser cutting speed at the start and much higher piercing speeds. The CO2 lasers also possess the ability to leave a smoother finish.
The use of fiber laser systems for laser cutting is an efficient way of material cutting and laser engraving as it is one of the most efficient and cost-effective ways to process large volumes of material.

High-power ytterbium-doped fiber lasers for biomedical applications

on October 17, 2017

Ytterbium-doped fiber lasers work in a near-infrared spectral window and are capable of high-power operation. They have gained popularity in the recent years due to their high-energy wideband operation. A wide range of physical attributes, like single longitudinal mode, also knows as single frequency, broad gain bandwidth, high power efficiency, outstanding thermo-optical properties and fully alignment-free design, makes them attractive for numerous applications, for example,  light bullet generation, optical frequency comb formation, materials fabrication, free-space laser communication, and biomedical diagnostics.

The high demand for ytterbium-doped fiber lasers has forced the fiber laser manufacturers to develop high-power ytterbium fiber lasers that are capable of producing femtosecond pulses. The continuous wave, femtosecond, picosecond operations of the ytterbium-doped fiber lasers have been intensively demonstrated.

Despite the recent developments in scientific fiber laser systems, ytterbium-doped fiber lasers are still limited in the spectral bands:  970-980 nm and 1030-1100 nm. The development of ytterbium fiber lasers that bridge this wavelength gap is important to achieve hyperspectral capability which is important for certain applications, some of which include multicolor two-photon excited fluorescence (TPEF) microscopy, hyperspectral coherent Raman scattering microscopy, etc. Fiber lasers doped with ytterbium will be able to interact with widely used biomolecules and dyes, reducing the illumination power required to work with the dyes.

Femtosecond ytterbium-doped fiber lasers are the most promising as they compare with visible light and can penetrate deeper into biological tissue without inflicting damage. The properties of femtosecond pulse fiber lasers are highly desirable for the following applications: advanced 3D micro-/ nano-structure processing, biological imaging, optical frequency comb formation.
