| 英文摘要 | The sideband and carrier of an electro-optic modulator (EOM) are usually used as Raman lasers in atom interferometry. To eliminate AC-Stark shift in atom interferometry, the stability of sideband to carrier ratio (SCR) is of great significance. We present a beating method to accurately measure and control the SCR. The influence of imperfect frequency response of the beating system is avoided by chirping the reference laser with half chirping rate of the modulation frequency. Making use of this method, we performed a SCR locking by feedback to the modulation depth. The locked SCRs' variation is averaged to be less than 0.1% within 20 MHz chirping span, and the according error for gravity measurement with 180 ms free evolution time is 6.2x10(-11)g. Thus both the SCR variation and the estimated gravity measurement error are reduced by about 2 orders. This work may provide hints to other EOM involving experiments.
