Enhanced efficiency and stabilized beam-power generation were proved for a high-brightness cw-based 500-W Nd:YAG rod laser by compensation of the thermally induced bifocusing of the Nd:YAG rod. Maximum laser power of 500 W cw was obtained at lamp input power of 18.4 kW, with beam quality M(2) = 19 orωθ (radius x, the half-angle of divergence) = 6.4 mm mrad and power fluctuation of less than 1%.
通过补偿钕钇铝石榴石（Nd:YAG）棒的热致双聚焦，证明了基于高亮度连续波的500瓦Nd:YAG棒激光器的效率提高和光束功率稳定产生。在灯输入功率为18.4千瓦的情况下，获得了500瓦连续波的最大激光功率，光束质量M² = 19或ωθ（半径x，发散半角）= 6.4毫米毫弧度，功率波动小于1%。
