Self-adaptive evaporative cooling semiconductor laser

The invention relates to a self-adaptive evaporative cooling semiconductor laser and belongs to the technical field of semiconductor lasers. The self-adaptive evaporative cooling semiconductor laser comprises a laser body, wherein an electrical-to-optical conversion module is arranged in the middle of the laser body, and positive and negative terminals of the electrical-to-optical conversion module are arranged on the surface of the laser body. The self-adaptive evaporative cooling semiconductor laser is characterized in that a liquid down groove and a gas up groove are arranged on the side wall of the laser body, upper ends and lower ends of the liquid down groove and the gas up groove are respectively communicated with a radiating condensation chamber and a liquid storage chamber stored with cooling media, and fans are arranged at the upper end of the laser body to correspond to the radiating condensation chamber. The self-adaptive evaporative cooling semiconductor laser is energy-saving, small in size, hig
