摘要
Abstract
In order to cope with changeable environment and complex requirements of strontium optical lattice clockexperiments, laser power should be stabilized and controlled in time sequence in some laser paths. Acousto-optic modulation wasadopted to stabilize the laser power based on the principle that diffraction efficiency of acousto-optic crystal varies with the changeof driving radio frequency power. A feedback control system was established to realize active stabilization of laser power andtiming control of power. The result shows that laser power can be set at arbitrary levels within its setting range according to timesequence. When the control system is enabled, the relative laser power stability is improved from 10 -2 to 10 -4 compared with thedisabled state. The advantage of the system is power stability with timing control.关键词
