The latest progress of high average power picosecond fiber lasers high power ultrashort pulse fiber laser in industrial processing, laser medical, scientific and military fields has a very important application, at home and abroad in recent years become a hot research and industrial development. Domestic research departments have done a lot of cutting-edge research in this field, including graphene-based, graphene oxide, SESAM saturable absorber and other all-fiber mode-locked fiber laser, the pulse width from a few dozen to several hundred picoseconds Minutes , repetition frequency from tens kHz to several megahertz, with an average power of up to one hundred watts mean, peak power up to hundreds of kilowatts, including 1.03 micron wavelength, 1.064 m, 1.5-1.6 micron episode 1.9-2.1 micron, etc. .
