内调制技术和Pound-Drever-Hall技术对894.6 nm倍频腔的稳频比较
Comparison of frequency locking of 894 . 6 nm frequency doubling cavity using intra-modulation technology and Pound-Drever-Hall technology
摘要
Abstract
In order to compare and select the technology of locking frequency of pump source, by using intra-modulation technology and Pound-Drever-Hall ( PDH ) technology separately, and choosing periodically poled KTP ( PPKTP ) crystal as nonlinear crystal, stable frequency operation of 894. 6nm continuous light two-mirror standing wave frequency doubling cavity was realized. The results show that frequency doubling cavity has the same blue light power output using two locking technologies and under different input light powers. 447. 3nm blue light of 178mW is obtained when the maximum fundamental light power of 350mW and the corresponding conversion efficiency is 50. 8%. Under the condition of the maximum fundamental power, the power fluctuation of blue light obtained by intra-modulation technology and PDH technology are 3. 4% and 2. 3% in 2h respectively. The research is helpful for preparing stable output of 447. 3nm blue light to obtain nonclassical light source at D1 line of cesium atom.关键词
