Detailed power and spectral analysis of a diode-pumped c-cut Pbnm 3 at.% Tm-doped yttrium aluminum perovskite (Tm:YAP) laser in a continuous wave (CW) operation is presented. The laser was experimentally examined in terms of the dependence on the transmittance and radius of curvature of the output coupling mirrors. At room temperature, for an output coupling transmission of 10.8%, the maximum output power of 6.35 W was obtained under a total absorbed pump power of 13.67 W with an optical-to-optical conversion efficiency of 46.5%. The highest slope efficiency of 60.4% was indicated. A detailed spectral analysis was presented. For its dependence on output coupler transmission, the Tm:YAP laser generates wavelengths at approximately 1940 nm or 1990 nm.

使用半导体可饱和吸收镜, 实现了光纤耦合半导体激光抽运Tm:YAP晶体的全固态连续波锁模激光运转。根据ABCD矩阵理论设计激光器参数, 通过控制谐振腔的像散和模式分布, 获得了稳定的皮秒锁模激光输出。当最大抽运功率为7.96 W时, 获得锁模激光的最大平均输出功率为0.73 W, 相应的斜效率为15.6%。此时锁模脉冲宽度约为1.7 ps, 对应的重复频率为88.7 MHz, 中心谱线为1 982.4 nm。结果表明: Tm:YAP晶体是一种具有较好的热学、机械性能的2 μm波段超快激光晶体。
