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。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＆#39;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.
