Abstract:
A high power Q-switched all solid state master oscillator power amplifier (MOPA) laser system is reported in this paper, which produces linearly polarized light 89 W at 500 Hz in 5.5 ns (FWHM). Bidirectional voltage supplied electro-optic Q-switched technology was used in oscillator stage, which obtained adjustable pulse width from 5.5 to 21 ns in 1064 nm. Through multistage Nd:YAG amplifiers at the pulse width of 5.5 ns, the oscillator laser power was scaled up to 89 W and the corresponding peak power reached 32.3 MW with power instability less than 0.51%.
