(1) fiber laser performance improvement: how to increase the power output and efficiency, optimization of beam quality, shorten the length gain and improve system stability and make it more compact is the focus of future research in the field of fiber lasers. 

(2) development of a new fiber laser: in terms of time, with smaller duty of Ultrashort-pulse mode-locked fiber laser is a laser research in the field of hot, high power femtosecond pulse fiber laser has been the long-term goal. In terms of frequency, wideband tunable fiber laser output and will become hot.
