Description

technical field [0001] The invention belongs to the field of laser technology, and relates to the problem of heat dissipation of high-power pump sources in the laser industry, in particular to a cooling structure for high-power pump sources. Background technique [0002] The pump source is a device that provides energy for the entire laser, and its operating temperature is very important. In order for the laser to work normally, the temperature of the pump source of the laser must be strictly controlled within a certain range, otherwise, these components will not work normally. Consequently, the desired laser light cannot be obtained. However, the pump source of the laser will generate a lot of heat when it is working. Therefore, with the operation of the laser, the temperature of these optical components will continue to rise. If the temperature of these components cannot be effectively reduced, the laser will not work. [0003] With the rapid development of the laser indu...

Problems solved by technology

At present, the laser industry mainly adopts air-cooled, deep-hole drilled water-cooled plates, high-temperature brazed water-cooled plates and other heat dissipation methods. These heat dissipation methods are low in efficiency and large in size, and cannot meet the heat dissipation requirements of high-power pump sources. The heat dissipation problem restricts a single pump. Puyuan develops in the direction of higher power
