Claim Text:
1. A bilateral cooling type semiconductor laser system for medical beauty use, comprising: a semiconductor laser array comprising a plurality of stacked semiconductor lasers, an optical waveguide disposed in front of a light emitting surface of the semiconductor laser array, a transparent contact window abutting against a light outlet end of the optical waveguide, a pair of cooling blocks for conduction cooling of the contact window, and a first water throughflow block; wherein, the semiconductor laser array is disposed on the second water throughflow block and an insulating barrier is disposed therebetween; the first water throughflow block comprises a base and a U-shaped head located on the base; middle and rear parts of the optical waveguide are embedded in the U-shaped head; a fixed block is disposed on a corresponding part of the optical waveguide to tightly press and fix the optical waveguide; a gap is provided between the optical waveguide and side walls of the U-shaped head; a pair of thermoelectric coolers and a pair of cooling blocks are sequentially and symmetrically disposed at outer sides of the U-shaped head; the pair of cooling blocks extends to a forepart of the optical waveguide and encircles side walls of the contact window and the forepart of the optical waveguide.
