Abstract

We report the second harmonic generation and fourth harmonic generation of the output from a short-pulsed (~ 80 ps) thulium-doped fiber laser, generating 976 and 488 nm wavelengths with high efficiency. With a narrow-linewidth (0.5 nm) pump at a power of 3.2 W, a second harmonic power of 2.4 W was generated at 976 nm with a conversion efficiency reaching 75%. For FHG, 690 mW of power at 488 nm was obtained from frequency doubling of 976 nm with a conversion efficiency of 30%.

摘要

我们报道了短脉冲（约80皮秒）掺铥光纤激光器输出的二次谐波产生和四次谐波产生，高效产生了976纳米和488纳米波长的光。在功率为3.2瓦、线宽为0.5纳米的窄线宽泵浦光作用下，在976纳米处产生了2.4瓦的二次谐波功率，转换效率达到75%。对于四次谐波产生，通过976纳米的倍频获得了488纳米处690毫瓦的功率，转换效率为30%。
