  • 摘要:

    基于大增益带宽和高热导率晶体的偏振复用激光技术可以提高双频激光器和双光梳激光器在输出光谱范围和功率方面的性能。本文提出一种基于Yb:CALGO晶体的偏振复用激光器。将两片与光轴成45°角切割的双折射晶体放置在增益晶体的前后两侧形成三明治结构,利用双折射晶体的偏振特性使腔内激光形成只在三明治结构部分具备空间分离其余部分共线的偏振方向互相垂直的两种模式。同时,这种三明治结构既能使单束泵浦光能够自动分离为两束空间分离匹配的泵浦光,也可以使腔内增益晶体放置在腔内模式腰斑位置处,与泵浦光达到更好的模式匹配,提高光泵浦效率。最终测得的激光输出功率达到瓦量级并且斜率效率超过30%。在腔内加入标准具后,实现了频差为太赫兹量级的稳定双频激光运转。

(a)−(c) show the spectra when no etalon was used, and (d)−(f) show the spectra when an etalon was used; (a) and (d) show the spectra when the o- and e-light coexisted, while (b), (c), (e), (f) show the spectra when only one polarization state was excited
