The invention provides a semiconductor laser and a semiconductor laser side pump module, and belongs to the technical field of lasers, and the semiconductor laser comprises an insulating water cooling plate, a plurality of laser units, a positive electrode lead-out plate, a negative electrode lead-out plate and a fixing assembly. The positive electrode lead-out plate is arranged between the insulation water cooling plate and the positive electrode plate in a penetrating mode and provided with two communication holes and first exposed parts, and protruding series connection parts are arranged on the second first exposed part to the last first exposed part in the preset direction. The negative electrode lead-out plate is attached to the negative electrode plate and is provided with second exposed parts, and the first to last second exposed parts in the preset direction are attached to the adjacent series connection parts in the preset direction. The fixing assembly and the insulation water cooling plate clamp all the positive electrode lead-out plates, the laser units and the negative electrode lead-out plates. According to the semiconductor laser and the semiconductor laser side pump module provided by the invention, the problem that the laser unit penetrates into the cavity and the angle of the laser unit is adjusted so that the laser unit is difficult to install can be avoided.
Description
technical field [0001] The invention belongs to the technical field of lasers, and more specifically relates to a semiconductor laser and a semiconductor laser side pump module. Background technique [0002] In existing semiconductor lasers, a plurality of laser units are water-cooled by an insulating water-cooling plate. The side of the insulating water-cooling plate is provided with a water inlet channel and a water outlet channel that are arranged in a straight line and are parallel to each other. There are multiple water outlet holes in the length direction, and there are multiple water inlet holes along the length direction of the water outlet channel on the water outlet channel. The water outlet holes and the water inlet holes are arranged in pairs. Each pair of water outlet holes and water inlet holes corresponds to a laser unit. There are two flow holes, and the laser unit is also provided with heat dissipation holes for communication between the two flow holes. The ...
