NIM稳频激光器在FG5-112绝对重力仪上的测试分析

Test Result of the NIM Frequency Stabilized Laser on the FG5-112 Absolute Gravimeter

利用中国计量科学研究院(NIM)研制的碘稳频He-Ne激光器替换FG5中使用的Winters Model 100碘稳频He-Ne激光器,并进行对比观测实验。实验表明,NIM的碘稳频He-Ne激光器能使FG5绝对重力仪正常工作,完全能够替代Winters Model 100碘稳频He-Ne激光器。

Using the National Institute of Metrology（NIM） designed iodine-stabilized He-Ne laser as a substitute for the FG5 ＇s Winters Model 100 iodine-stabilized He-Ne laser, we do some experiments of comparison. The test results show the NIM＇s iodine-stabilized He-Ne laser can properly work with FG5 absolute gravimeter, and the NIM＇s iodine-stabilized He-Ne laser could totally take the place of the original Winters Model 100 iodine-stabilized He-Ne laser.
