摘要	A high-power fiber laser with a master oscillator power amplifier (MOPA) structure is constructed by using pump sources and large mode area ytterbium doped fiber (LMA). Lasers include three parts: seed laser source, preamplifier and main amplifier. The fiber laser is integrated with air cooling structure. When the pulse is set to 200 ns 100 kHz, the fiber laser has an air cooling structure, the maximum pump power is 210 W, the 124 W is obtained. The wavelength is the stable output of the 1064 nm laser, the conversion efficiency is 59 %, the single pulse energy is 1.24 mJ, the peak power is 6.2 kW, the laser beam quality is M = 1.38, and the power stability is within 2 %. At present, the output power of laser is limited by pump power, and the increase of pump source is expected to further improve output power.
