| 摘 要： | 基于KTP键合晶体采用Hansch-Couillaud频率锁定技术实现了双波长外腔同时共振,理论和实验上分别研究了基于键合KTP晶体的HC频率锁定方案. 研究表明,与采用单KTP晶体的结果相比,采用键合KTP晶体进行HC锁频时,能将激光频率分别锁定到e1光或e2光的共振峰值. 实验中将环形腔腔模频率锁定到938nm激光器的输出频率上,1583nm激光器的输出频率锁定到环形腔腔模频率上,从而实现了三者之间的相位关联锁定.

| Abstract: | Dual-wavelength external cavity resonance is achieved by Hansch-Couillaud(HC) frequency locking technology based on diffusion bonded KTP crystal. The HC frequency locking scheme based on diffusion bonded KTP crystal is analyzed theoretically and experimentally. The results show that the laser frequency can be locked to the resonance peak of e1-light or e2-light, compared with the results of a single KTP crystal. The longitude mode frequency of bow-tie cavity is locked at the frequency of 938nm laser firstly, and then the longitude mode frequency of bow-tie cavity is locked at the frequency of 1583 nm laser. The phase correlated locking of three components is realized. |
