摘要
基于小型化多波长选择输出的Nd∶YVO4固体自拉曼激光器, 理论分析了其激光晶体内的热应力分布, 得出热破裂易发生的位置, 与实验结果吻合。搭建实验平台研究了激光晶体热破裂对激光器各个波长激光输出功率的影响。实验结果表明, 热裂前后1064nm基频光阈值及输出功率变化不大, 而532、559及588nm激光阈值分别由0.2W升至0.43W、0.3W升至1.5W和0.3W升至1.5W, 最大输出功率分别由560mW降至131mW、600mW降至50mW及200mW降至26mW。
Abstract
Based on the miniaturized multi-wavelength selective output Nd∶YVO4 solid self-Raman laser, the thermal stress distribution within the laser crystal was theoretically analyzed, and the locations where the thermal cracking easily occurs were obtained, which is consistent with the experimental results. An experimental platform was set up to study the effects of laser crystals on the laser output power at various wavelengthes after thermal cracking. Experimental results show that the threshold and output power of the 1064 fundamental frequency laser before and after thermal cracking do not change much, but the laser threshold at 532, 559 and 588nm increases from 0.2 to 0.43W, 0.3 to 1.5W and 0.3 to 1.5W, respectively, while the maximum output power is reduced from 560 to 131mW, 600 to 50mW, and 200 to 26mW, respectively.
