Fiber laser cooling device

Abstract

The invention discloses a fiber laser cooling device. The fiber laser cooling device comprises a bearing assembly, a water cooling assembly, a laser body and an air cooling assembly; the bearing assembly comprises a connecting plate, a supporting frame and a box body; the water cooling assembly comprises a sleeve, a heat exchange coil pipe, a water pump, a water inlet hose and a water drainage hose; the laser main body comprises a shell, a pumping source and a resonant cavity; and the air cooling assembly comprises an air inlet pipe, a plurality of cooling fans and a plurality of cooling fins.Overall supporting is achieved through the bearing assembly, and connection with an external use part is facilitated through the connecting plate; cold water is introduced into the heat exchange coilthrough the water pump for heat exchange, heat conduction is conducted through the elastic heat conduction silica gel sleeve, and a good water cooling effect is achieved. Through the cooperation of afirst fixing ring and a second fixing ring, the shell is simply and conveniently mounted in the sleeve, so that the laser main body is convenient to mount and dismount; and hot air is exhausted through the heat dissipation fan, and heat dissipation is conducted through air cooling.

Description

technical field [0001] The invention relates to the technical field of laser cooling, in particular to a fiber laser cooling device. Background technique [0002] Fiber laser refers to a laser that uses rare earth element-doped glass fiber as the gain medium. Fiber laser can be developed on the basis of fiber amplifier. Under the action of pump light, it is easy to form high power density in the fiber, resulting in the laser of the laser working substance. The energy level is "particle number inversion". When properly added to the positive feedback loop, the laser oscillation output can be formed. The application range of fiber laser is very wide, including laser fiber communication, laser space long-distance communication, industrial shipbuilding, automobile manufacturing, laser engraving and laser printing. Laser cutting, printing rolls, metal and non-metal drilling / cutting / welding (brazing, quenching, cladding and deep welding), military defense security, medical equipmen...

AI Technical Summary

Problems solved by technology

[0003] During the operation of the fiber laser, a certain amount of heat is generally generated. If it is not cooled in time, it will affect the effect of the laser emitting laser and its service life. Currently, water cooling is generally used for cooling the fiber laser. Although it can To achieve the effect of cooling, however, it is difficult to cover the adjacent components only by water cooling, which causes the heat emitted by the surrounding electrical components to affect the laser, which is not conducive to the cooling of the fiber laser
