Experiment research of 100 W, all-fiber acousto-optic Q-switched fiber laser

We report a high-power all-fiber format pulsed laser source at ~1064 nm 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 ~1 W, and two double-cladding Yb-doped fiber amplifiers were used to boost the average power of the seed. >230 W average power was achieved for ~1.4 μs pulses at 100 kHz repetition rate. The optical-to-optical efficiency of the main amplifier is 72.81%.

This paper presents a comprehensive experimental study of multi-stable-state output characteristics in an all-fiber laser with an acoustic-optical modulator (AOM) as the Q-switcher. For the first time, in this structure, the partitioning of the pulsed output characteristics is explored, dividing the operating status of the laser system into four zones. The output characteristics, the application prospects, and the parameter setting rules for working in stable zones are presented. In the second stable zone, a peak power of 4.68 kW with 24 ns was obtained at 10 kHz. This is the narrowest pulse duration achieved with an AOM actively Q-switched all-fiber linear structure. The pulse narrowing is attributed to the rapid release of signal power and pulse tail truncated by AOM shutdown.
