Global importance of fiber laser technology
Fiber laser technology is an advanced field of modern science, with researchers from various countries actively developing new solutions. Last year, scientists in Russia demonstrated a newly developed and successfully tested soliton fiber laser.
Russian researchers highlighted that fiber lasers are fundamentally important for scientific progress worldwide. Fiber lasers with high pulse repetition rates are particularly in demand in photonics, a promising counterpart to electronics.
Unique features of the soliton fiber laser
Double pulse stabilization and compact design
The newly developed soliton fiber laser features double pulse stabilization, compactness, reliability, and convenient laser beam delivery. Its design relies on fiber optics, which allow part of the energy to be emitted into the laser cavity. Double synchronization aligns the phases of longitudinal waves, producing ultra-short, powerful pulses. After several radiation cycles, the pulses form stable solitons.
High-frequency pulses and pulse train quality
Due to double stabilization, scientists developed a fiber laser that combines high-frequency pulses with a high-quality pulse train. The design uses nonlinear polarization rotation and frequency shift effects generated by an optical modulator. This allows harmonic synchronization of longitudinal waves in any generation mode. The next goal is to further enhance the fiber laser’s performance.
Fiber laser history and applications
Development milestones
Since the creation of the first fiber laser, the technology has proven highly effective across multiple fields. For example, fiber lasers revolutionized ophthalmology just three years after their introduction. At each stage, challenges were addressed in medicine, industry, quantum computing, fundamental science, and more. Today, fiber laser systems have a wide range of applications.
New types of fiber lasers continuously open up unique and previously unforeseen applications. Advancements in fiber laser technology play a key role in scientific and applied research success.
