研究了激光二极管端面抽运Tm,Ho∶YLF连续激光器的输出特性,并对激光器的参数进行了优化.在考虑能量传递上转换的前提下,通过准三能级速率方程推导出了连续抽运Tm,Ho∶YLF激光器输出功率与抽运功率关系的表达式.对激光晶体的粒子掺杂浓度、晶体长度、激光束腰半径与抽运光束腰半径比值以及输出镜透过率等激光器参数进行了优化.实验上得到了激光输出功率随抽运功率的变化关系,并将其与理论结果进行了比较,发现比较吻合,从而验证了理论模型的合理性.
The output characteristics of the laser diode Tm, Ho:YLF continuous laser are studied and the parameters of the laser are optimized.Under the premise of energy transfer upconversion, the continuous pumping Tm, Ho: YLF laser output power and pumping power of the expression of the laser crystal particle doping concentration, crystal length, laser beam waist radius and pumping beam waist radius ratio and the output of the laser transmission parameters such as laser parameters The experimental results show that the laser output power changes with the pumping power, and compared with the theoretical results, it is found that they are in good agreement with each other to validate the rationality of the theoretical model.
