使用共振多程光声池的CO2和SF6的无多普勒饱和吸收光谱
Doppler-free saturated absorption spectroscopy of CO2 and SF6 molecules by using a resonant optoacous tic multipass cell (MPC)
摘要
本文使用共振多程池的光声探测法对CO_2和SF_6分子的无多普勒饱和吸收光谱进行了实验研究.测量CO_2的吸收凹陷约为2.5MHz,实验中观察到5个SF_6的吸收凹陷、凹陷深率约为1.9MHz.两种情况的分辨率均大于10~7.
Abstract
The Doppler-free saturated spectroscopy of the CO2 and SF6 molecules is investigated experimentally by using optoacoustic detection with a resonant multipass cell. The width of the absorption dip for CO2 is measured to be about 2.5 MHz, five absorption dips for SF6 are observed in the experiments, and the dip width is about 1.9MHz. In both oases the spectral resolving power is greater than 107.
