摘要
报道了激光二极管(LD)三向侧面抽运Tm,Ho∶LuLiF激光器热效应的实验研究。理论上计算了激光介质内抽运光强的分布, 分析了不同抽运光束腰下, 对抽运光强和均匀性的影响。利用有限元分析, 模拟了抽运时介质内部温度分布轮廓图。将激光晶体热透镜效应作类透镜近似, 进行实验测量。利用通过小孔的高斯光束光强变化, 拟合出He-Ne光通过晶体前后的高斯光束形状; 近似成高斯光束经薄透镜的变换, 计算得出在抽运单脉冲能量3.3 J, 脉冲重复频率10 Hz下, Tm,Ho∶LuLiF晶体的热透镜焦距约为-2.3 m, 实验结果与理论预测基本相符。
Abstract
Experimental results of thermal effect in laser diode (LD) three-direction side-pumped Tm,Ho∶ LuLiF laser are reported. It is calculated of the distribution of pump intensity in the laser medium. The effects on the pump intensity and uniformity under different pump waists are analyzed. Temperature distribution in the laser media is simulated by finite element analysis. Considering the laser medium as lenslike, the experiment measuring is developed. Using the intensity changing of Gaussian beam through small aperature, the Gaussian beam shapes of He-Ne laser through the laser medium is fitted. Caculating from the approximate transformation of Gaussian beam by thin lens, the thermal focal length of Tm,Ho∶LuLiF crystal is about -2.3 m with pump pulse power of 3.3 J and pulse repetiton frequency of 10 Hz. The experimental result is in agreement with the theoretical prediction.
