【摘要】：为了对抽运源的稳频技术做出对比和选择,采用内调制技术和相位调制光外差技术,以周期性极化KTP晶体作为非线性晶体,实现了894.6nm连续光两镜驻波倍频腔的稳频运转。结果表明,在不同注入光功率下,用这两种方法锁定倍频腔后获得的蓝光功率基本相同;在最大注入光功率为350m W时,获得178m W的447.3nm蓝光,相应的转化效率为50.8%;在最大注入光功率下,利用内调制技术和相位调制光外差稳频技术获得的蓝光在2h内功率起伏分别为3.4%和2.3%。该研究对获得稳定输出的447.3nm蓝光用来制备铯原子D1线的非经典光的实验是有帮助的。
[Abstract]:In order to compare and select the frequency stabilization technique of pump source, the frequency stabilization of 894.6nm continuous optical two-mirror standing wave doubling cavity is realized by using internal modulation technique and phase-modulated optical heterodyne technique, using periodically polarized KTP crystal as nonlinear crystal. The results show that the blue light power obtained by the two methods is basically the same under different injection optical power, and 178MW 447.3nm blue light is obtained when the maximum injected optical power is 350 MW, and the corresponding conversion efficiency is 50.8 MW. Under the maximum injection power, the power fluctuation of blue light obtained by internal modulation technique and phase modulated heterodyne frequency stabilization technique is 3.4% and 2.3% within 2 hours, respectively. This study is helpful to obtain stable output 447.3nm blue light used to prepare non classical light of cesium D1 line.
