Abstract

The invention discloses a laser light source for using laser to pump a small cesium atomic clock. The light source comprises a base. A thermal insulation cover is arranged at the upper side of the base, and connected with the base. A semi-conductor refrigerating device is arranged at the upper side of the base, connected with the base and located in the thermal insulation cover. A heat conducting plate is arranged at the upper side of the semi-conductor refrigerating device, connected with the semi-conductor refrigerating device and located in the thermal insulation cover. A laser machine is arranged at the upper side of the heat conducting plate, connected with the heat conducting plate and located in the thermal insulation cover. PCBs are arranged at the upper side of the base, connected with the base, and are located at two sides of the heat conducting plate. Laser machine fixing clamps are arranged at two sides of the laser machine, and connected with PCBs. A laser hole is formed in the side facing squarely the laser machine, of the thermal insulation cover. A socket connected with the base is arranged at the upper side of the base. A socket installation hole is formed in the thermal insulation cover. The laser light source for using laser to pump a small cesium atomic clock is better in beam stability. At the same time, secondary temperature control and magnetic shielding can reduce the influence caused by temperature and electromagnetic interference to the wavelength and intensity of the laser output.

Description

technical field [0001] The invention relates to a laser light source applied to a small cesium atomic clock pumped by laser. Background technique [0002] With the continuous development of electronic technology, laser light sources are widely used in various aspects such as industry, agriculture, precision measurement and detection, communication and information processing, medical treatment, military affairs, etc. People's requirements for laser light sources are also getting higher and higher.
