【Abstract】 The stability of a three-rods Nd∶YAG laser system was analyzed by the matrix theory of resonator. The stable range of a symmetric plane-plane resonator was calculated, and the result showed that the output power could be increased by a suitable choice of rods position. The stable range will be reduced if the thermal effects of the three Nd∶YAG rods are not the same. The maximum output power of 970?W was attained in experiments.更多还原
