传统532 nm波长碘稳频固体激光频标装置虽然能达到很高的频率稳定度和不确定度，但装置比较庞大，不便搬运。而对于一些对激光频率稳定度要求不高的实际应用，如绝对重力仪等，缩小装置的体积以易于搬运，成为更为关注的因素。建立一套小型化532 nm固体激光器，该系统体积小巧，易于搬运。通过与原有碘稳频532 nm固体激光标准装置的进行拍频测量实验，得到1 s的阿伦偏差为2.4×10-12，并计算得到该激光器的频率绝对值为563260223436 kHz，对应的频率不确定度为52 kHz(包含因子k=2)。该系统已被用于中国计量科学研究院的绝对重力仪中。

Although the traditional iodine-stabilized 532 nm optical frequency standard is high frequency stability and uncertainty, it is complex and not portable. Lower frequency stability is acceptable in some cases such as absolute gravimeters, on which smaller size and portable are focused. A compact iodine-stabilized solid-state laser at 532 nm is established, which is portable for its small size. By the way of measuring the frequency beat with the original iodine-stabilized 532 nm optical frequency standard, the Allan deviation is 2.4×10-12 for 1 s averaging time, and the absolute frequency of the laser is 563260223436 kHz, whose uncertainty is 52 kHz (coverage factor k=2). The system has been applied to absolute gravimeters at National Institute of Metrology.
