摘　　要：简要介绍ML-1型稳频激光器的红、蓝光工作模式,对其单光、双光测量结果进行实验,并与FG5X型绝对重力仪的观测结果进行对比。结果表明,ML-1型激光器红、蓝光工作模式可有效减小稳频激光器温度及时间的漂移对绝对重力观测的影响,红蓝分离值的大小表征了激光器漂移的程度,若红蓝分离值较大,表明稳频激光器存在较大漂移,需进行标定校准。This paper introduces the working modes of ML-1 frequency-stabilized laser.The results of single mode and two modes measurements are compared with those of the FG5X absolute gravimeter.We show that the working modes of ML-1 laser can effectively reduce the influence of temperature drift and time drift on absolute gravity observation.The red/blue separation indicates the laser drift.When the red/blue separation is large,it indicates that there is a large drift in the frequency-stabilized laser,which needs calibration.
