Stacked-array liquid refrigeration type high-power semiconductor laser

The invention provides a stacked-array liquid refrigeration type high-power semiconductor laser, and particularly relates to a macro channel liquid refrigeration stacked-array semiconductor laser. The stacked-array liquid refrigeration type high-power semiconductor laser comprises a lower water drainage block, an insulation sheet a, a positive electrode, a semiconductor laser module, a negative electrode, an insulation sheet b and an upper water drainage block, and the lower water drainage block, the insulation sheet a, the positive electrode, the semiconductor laser module, the negative electrode, the insulation sheet b and the upper water drainage block are sequentially arranged from bottom to top. The semiconductor laser module is formed by stacking a plurality of semiconductor laser units, liquid refrigeration sheets of a sheet structure are adopted by the semiconductor laser units, and water drainage areas and chip mounting areas are arranged on the liquid refrigeration sheets. The micro channel refrigeration structure is adopted in the stacked-array liquid refrigeration type high-power semiconductor laser, a plurality of sets of through holes are adopted as refrigeration channels, the structure is simple, compared with a microchannel refrigeration structure, the requirement for the granularity of refrigerant fluid is not high, the risk of corroding the liquid refrigeration channels is low, and the reliability of the semiconductor laser is improved.
