摘要
以准三能级固体激光理论为基础,用数值方法研究了LD边抽运Yb∶YAG板条激光器的激光输出特性、温度效应、光学畸变和摩尔分数优化等性能。计算表明,Yb∶YAG可实现 100kW的激光输出,板条的尺寸在 130mm×60mm×3mm左右,Yb3+的摩尔分数小于 1%。从晶体的生长的角度看,生长出满足 130mm×60mm×3mm晶体元件加工需求的Yb∶YAG晶体是可行的。所以,Yb∶YAG是未来激光战术武器中的候选材料。
Based on the theory of quasi-three-level solid-state laser,the laser properties of LD edge-pumped Yb∶YAG slab laser are studied with numerical calculation method.The laser output properties,temperature effect,optical distortion and doped concentration optimization are studied.The calculation results indicate that 100kW laser output can be achieved with Yb∶YAG medium,whose size is about 130mm×60mm×3mm and Yb 3+ concentration should be less than 1%.It is feasible to grow the crystal with size of 130mm×60mm×3mm,so Yb∶YAG is a promising material used in the tactical laser weapons.
