由热应力决定的高功率连续Nd:YAG激光器的最大泵浦功率
Maximum pumping power for high power CW Nd:YAG laser limited by thermal stresses
摘要
本文报导了一台累积寿命为50小时的高功率连续激光器(更换一次氪灯)。其最大输出功率为366W,并研究了该激光器的输出特性和稳定性.此外,从实验上测量了激光棒内部耗散的功率,分析了Nd:YAG晶体棒中的温度和热应力,指出了高泵浦功率下热应力的存在是棒发生炸裂的主要原因,并确定每根棒的最大泵浦功率.
Abstract
The problems have been investigated concerning the output properties and accumulative life of a high power CW Nd:YAG laser with many hundreds watts output, and the rupture of Nd:YAG rod induced by high pumping power has been analysed.
