Abstract: Disclosed is a high power VCSEL laser treatment device with a skin cooling function, comprising VCSEL array packaged on a laser heat sink, an optical transmission device arranged in front of light-exiting faces of the VCSEL array and a high-heat conductivity optical window sheet adhered to the light-exiting port end of the optical transmission device. An integrally molded cooling conduction metal piece is arranged on the outer sides of the laser heat sink, the optical transmission device, and the high-heat-conductivity optical window sheet. In addition, one or more semiconductor chilling plates are arranged between the cooling conduction metal piece and the laser heat sink. In the above-mentioned high power VCSEL semiconductor laser treatment device, the semiconductor chilling plates and the VCSEL array share the heat sink, so that the inner structure is simplified.

Abstract: Provided is a high-power semiconductor laser based on VCSEL, comprising a VCSEL laser module. The VCSEL laser module includes a VCSEL chip array (1) consisting of a plurality of VCSEL chips (10) and an inner wall reflection optical transmission device (2) which is arranged in front of a light emergent face of the VCSEL chip array (1); and the light emergent face of the VCSEL chip array (1) is used for secondarily reflecting the reflected light reflected by a target object (3) and the inner wall reflection optical transmission device (2). Also provided is a packaging structure for the high-power semiconductor laser. The VCSEL chip array (1) is packaged by an inwardly concave arc-shaped heat sink (4), so that the purpose of converging the laser light beam near a centre position can be achieved.
