PDH技术中F-P腔特性对鉴频曲线的影响

Influence of Fabry-Perot cavity on frequency discrimination curve in Pound-Drever-Hall method

  • 摘要: 详细介绍和分析了基于Pound-Drever-Hall(PDH)方法的激光器稳频技术.仿真分析了法布里-珀罗(F-P)腔镜面反射率及腔内损耗对鉴频曲线的影响,当反射率为0.2、不考虑腔内损耗时,鉴频曲线线性动态范围和灵敏度分别为9.6 MHz和0.2 MHz-1.与此同时,当腔内损耗为1%时,线性动态范围和灵敏度变化为14.5 MHz和0.05 MHz-1.结果证明了镜面反射率及腔内损耗都会对鉴频曲线产生显著影响.

     

    Abstract: A laser frequency stabilization technique based on Pound-Drever-Hall(PDH) method was introduced and analyzed in detail. The influences of the Fabry-Perot(F-P) mirror's reflectivity and loss of F-P cavity were analyzed by numerical simulation. The theoretical linear dynamic range(LDR) and sensitivity were 9.6 MHz and 0.2 MHz-1 without loss respectively if the reflectivity was 0.2. Meanwhile, the LDR was less than 14.5 MHz and the sensitivity preceded 0.05 MHz-1 in a situation considering that the cavity loss was about 1%. The results demonstrate that both the two factors cause significant influence on the LDR and sensitivity of the system.
