摘要
为建立一个高效率的基模振荡器模型,采用谐振腔理论和ABCD定律计算分析了热透镜对腔内模式的影响,研究了不同泵浦源对斯托克斯因子的影响。研究结果表明,在热透镜焦距300-350mm范围内腔模变化较小,采用914nm泵浦源可以提高斯托克斯因子从而提高振荡器效率。设计的基模振荡器在泵浦功率为50 W时,可得到34.7 W的激光输出,效率达到69.4%。
In order to setup a model of a fundamental mode oscillator with high efficiency, effects of the thermal lens on the cave mode are analyzed by using the oscillator theory and ABCD laws and influence of pump source on the Stokes factor is also studied. The results indicate that changes of the cave mode is small when the thermal focus is in the range of 300-350 mm. The Stokes factor increases by using 914 nm pump power and thus the efficiency of the oscillator can be enhanced, The output power of the designed fundamental mode oscillator is 34. 7 W with efficiency of 69.4% when pump power is 50 W.
