Abstract

We report a high-power all-fiber format pulsed laser source at 1064nm in a master oscillator–power amplifier configuration. The seed source is an acousto-optic Q-switched fiber laser with a varied pulse duration and repetition rate. The output power of the oscillator is 1W, and two double-cladding Yb-doped fiber amplifiers were used to boost the average power of the seed. >230W average power was achieved for 1.4μs pulses at 100 kHz repetition rate. The optical-to-optical efficiency of the main amplifier is 72.81%.
