Embodiment Construction

[0014] The present invention is further illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0015] Specific embodiments of the present invention are structured as Figure 1 As shown, the present invention relates to a SERF atomic gyroscope laser frequency stabilized power optical path system, comprising saturation absorption frequency stabilized optical path 1, liquid crystal laser power stabilized optical path 2. 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 achieve stable power. Liquid crystal laser power stabilized 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 beam shaping, and the second beam enters the power tran...

Abstract

The invention relates to an optical path system for laser frequency stabilization and power stabilization of a SERF atomic gyroscope. The system includes two parts: a saturated absorption frequency stabilization system and a liquid crystal laser power stabilization and beam shaping system. The saturated absorption frequency stabilization system is used to stabilize the frequency of the pumped light of the SERF atomic gyroscope, and the liquid crystal laser power stabilization system is used to stabilize the power of the pumped light of the SERF atomic gyroscope. Shaping, so that it changes from a laser with Gaussian energy distribution to a flat-top laser with uniform energy distribution. The invention has reasonable optical path layout, compact structure, convenient installation and adjustment, and simple experimental operation, which provides a basis for the development of high-precision and miniaturized SERF atomic gyroscopes.

Description

Technical field [0001] The present invention relates to the technical field of SERF atomic gyroscope, specifically relates to a SERF atomic gyroscope laser frequency stabilized power optical path system, the laser frequency stability power stable power optical path system, optical path layout is reasonable, compact structure, easy installation and adjustment, simple experimental operation, for high-precision miniaturized SERF atomic gyroscope development provides a basis. Background [0002] Navigation technology is of great significance to national defense construction and the development of the national economy. Inertial navigation is the only real-time, autonomous, continuous, hidden, no time and geographical restrictions, free from external interference navigation technology, is widely used in the national economy and military fields. The gyroscope is the core component of the inertial navigation system and the bottleneck that restricts the performance improvement of the ine...
