- The concept of viffoal laser frequency stabilizaion is put fowi . the frequency stabilizaion at the center of doppler curve has been realized aller signal detecting , phase sensitive detecting , integrating and high voltage amplifying circuits with fm spectroscopy a frequency stability of l0 - , has been obtained with a reproducibility of l0 - 9 . hyperfine spectra of , ' , i , near 532nm have been studied via modul8tion tfansfer spectroscopy
利用fm光谱法将激光单次通过碘吸收室进行线性吸收，再经信号检测、混频、积分和高压放大等伺服电路，实现了在多普勒曲线中心处的频率稳定，频率稳定度和复现性可达10 ~ ( - 9 )量级。
