摘要：
The hold-off capacity of high-power repetitively acousto-optic Q-switched Nd:YAG rod laser with different placement methods in the flat-flat cavity is explored in detail. Five types of typical placement are illustrated and it is confirmed that two orthogonally placed longitudinal wave Q-switches which are placed at the larger beam width in the laser cavity have better performance than others in terms of the theory, simulation and experiment. An average power of 408 W along with 79 ns pulse width at 15 kHz is obtained with 12.98% electro-to-optical efficiency and 344 kW peak power.
