(1) The improvement of the performance of the fiber laser itself: how to improve the output power and conversion efficiency, optimize the beam quality, shorten the gain fiber length, improve the system stability and make it more compact is the focus of future research in the field of fiber lasers.
(2) Development of new fiber lasers: In terms of time domain, ultrashort pulse mode-locked fiber lasers with smaller duty cycles have always been a hot spot in the field of lasers, and high-power femtosecond pulse fiber lasers have always been the long-term pursuit of people. In the frequency domain, fiber lasers with wideband output and tunable will become a research hotspot.
The research of fiber lasers has begun since the end of the 80s of the last century, because it can produce ultrashort pulses, has a very broad application prospects, so countries around the world have shown great enthusiasm for fiber laser research. Compared with other types of lasers, fiber lasers have outstanding advantages such as high reliability, simple structure, low price and high conversion efficiency.
