Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0015] The specific implementation structure of the present invention is as figure 1 As shown, the present invention relates to a frequency-stabilized and power-stabilized optical path system for SERF atomic gyroscope lasers, including a saturated absorption frequency-stabilized optical path 1 and a liquid crystal laser power-stabilized optical path 2 . The saturation absorption frequency stabilization optical path 1 divides the beam into two beams, the first beam is used for saturation absorption frequency stabilization, and the second beam enters the liquid crystal laser power stabilization optical path 2 to realize power stabilization. The liquid crystal laser power stabilization optical path 2 divides the beam into two beams. The first beam is used for lasers with stable output frequency and power and uniform spot energy distribution after ...
