【摘要】 研制了多普勒频率调制器（ＦＭ），当驱动电压频率为１７３Ｈｚ时，对于ＣＯ２激光获得３００ｋＨｚ的调频宽度。该调制器已成功地用于ＳＦ６分子的饱和吸收微分光谱的检测和将ＣＯ２激光频率稳定到ＳＦ６分子的吸收线中心的工作中．更多还原

【Abstract】 A new Doppler frequency modulator (DFM),driven by an audio oscillator,has been developed.Morethan 300 kHz of modulated frequency of CO2 laser is obtained when the DFM vibrates at 173 Hz.We have recorded the differential spectrum of saturated absorption lines of SF6 and locked CO2 laser frequencies in the centers of several absorption lines of SF6.更多还原
