摘要
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. The high-power semiconductor laser based on VCSEL has a wide application prospect in the laser medicine and industrial laser processing fields.
