Fiber lasers for production applications

The use of fiber laser systems for production applications is growing as on price per watt, beam quality, and electrical consumption fiber lasers provide the highest performance and lowest costs. The applications of fiber laser systems are constantly expanding – from traditional cutting and welding to more advanced 3D printing and surface texturing. Laser technology...


Narrow bandwidth fiber lasers

Laser linewidth is the spectral linewidth of a laser beam. More precisely, it is the width of the power spectral density of the emitted electric field in terms of frequency, wavenumber or wavelength. The laser linewidth is related to its temporal coherence that is characterized by the coherence time or coherence length. Single frequency lasers...


Fiber laser systems in photomask repair

A photomask is an opaque plate with holes and transparent areas that allow light to go through the plate in a specific pattern. Photomasks are widely used in photolithography for the production of integrated circuits, photonic devices, and micro-electro-mechanical systems. Usually, a photomask consists of fused silica or glass substrate that is coated with an...


Nanosecond, picosecond, femtosecond fiber lasers in micromachining

The goal of micromachining is to achieve high-quality results in the shortest time possible and in the most economical way. Laser machining can achieve all of these goals — it can achieve localized, high-quality, precise machining. However, the right choice of laser is crucial to achieving high-yield, economical process. Laser micromachining is heavily used in...


High beam quality fiber lasers in laser beam welding

Laser beam welding is a technique of material welding through the use of a laser beam. Laser beams provide a concentrated source of heat that allows for narrow welds and high welding rates. Laser beam welding is frequently used in high volume applications that are automated, i.e. in the automotive industry. The high power density...
