激光频率标准是将激光频率锁定于原子或分子的超精细能级间的稳定跃迁频率 ,从而获得高精度的激光频率输出[1- 3 ] 。激光频率标准的重要应用是进行精密光谱的测量 ,由于光谱数据是数据库中重要的一员 ,它不但可应用于计量、物理、化学、生物等基础领域 ,也广泛应用于能源、精
The laser frequency standard is to lock the laser frequency to the stable transition frequency between the ultrafine levels of atoms or molecules to obtain high-precision laser frequency output [1-3]. The important application of the laser frequency standard is the measurement of the precise spectrum. Since the spectral data is an important part of the database, it can be applied not only to basic fields such as metrology, physics, chemistry and biology but also to energy and fine
