从准三能级Yb离子的能级结构出发,建立了Yb离子的抽运和激光速率方程,结合解析和数值方法,研究了Yb激光介质的抽运动力学过程,包括抽运激发效率、最低抽运强度、激光能量提取效率等关键参数.比较了三类典型的Yb激光介质性能:Yb:S-FAP,Yb:YAG以及Yb:FP-glass.以放大自发辐射(ASE)为设计判据,重点研究了脉冲储能型Yb激光器的设计准则,包括增益介质的厚度与掺杂浓度.最后利用此模型给出了基于Yb:S-FAP以及Yb:YAG的100J级二极管抽运固体激光器(DPSSL)的总体设计参数.将对基于Yb激光介质的脉冲储能型DPSSL的设计提供有益的参考.
Based on the energy level structure of quasi-three-level Yb ions, the pumping and laser velocity equations of Yb ions are established. The kinetics of pumping kinetics of Yb laser medium is studied by the analytical and numerical methods. The pumping excitation efficiency, Such as Yb: S-FAP, Yb: YAG and Yb: FP-glass, were compared with the typical parameters of Yb laser medium.According to the design criterion of amplified spontaneous emission (ASE) This paper focuses on the design criteria of pulse energy storage Yb laser, including the thickness and doping concentration of the gain medium.Finally, 100J diode-pumped solid state laser (DPSSL) based on Yb: S-FAP and Yb: YAG ), Will provide a useful reference for the design of pulse energy storage DPSSL based on Yb laser medium.
