56J High energy high beam quality lamp pumped Nd:YAG solid-state laser

A 56J high frequency high frequency lamp pumped Nd:YAG laser is reported. The main factors influencing that the laser outputs high energy is firstly analyzed, and then bring forward the effective measures to improve the efficiencies of the laser, then develop a laser with its pulse width tunable between 0.1ms and 10ms, frequency between 1Hz and 1000Hz. When the laser inputs 12kw electrical power , it can outputs max single energy 56J , average power 500w with its beam parameter product 16.5mm.mrad、total electro-optics efficiency 4.2%、the stability of output power .
