【Abstract】 Virtual confocal polarization coupling output cavity Nd:YAG pulsed repetition Q-switching laser with amplifier stage is studied and its designing steps, experimental results are given in this paper. The output pulsed energy of oscillator is 250mJ, pulse width 12ns, TEM₀₀ mode outPut, output pulsed energy with an amplifier stage is not less than 500mJ, beam divergence less than 0.5 mrad, in near field light spot intensity distribution is even and in far field that is with a Gaussion distribution.更多还原
