Abstract

A high-power all-fiber ytterbium-doped picosecond fiber laser was developed using the main oscillation power amplification (MOPA) structure. The seed laser source was based on a novel two-dimensional perovskite material ((CH3NH3) PbI3) as a saturable absorber, achieving a stable picosecond with the center wavelength of 1063.8nm, the repetition frequency of 18.51MHz, the linewidth of 5nm, and the average power of 10.56mW. Based on this, four-stage pre-amplification and one-stage main power amplification were used to achieve high-power picosecond pulsed all-fiber laser output. The center wavelength is 1064.7nm, the linewidth is 8nm, the pulse width is 17.2ps, and the repetition frequency is 100MHz. The average output power is 51.5W, and the optical conversion efficiency is 56%.
