Disclosed is a high power VCSEL (vertical-cavity surface-emitting laser) laser treatment device with a skin cooling function, comprising VCSEL arrays (4) packaged on a laser heat sink (2), an optical transmission device (8) arranged in front of light-exiting faces of the VCSEL arrays (4) and a high-heat-conductivity optical window sheet (6) adhered to the light-exiting port end of the optical transmission device (8). An integrally molded cooling conduction metal piece (1) is arranged on the outer sides of the laser heat sink (2), the optical transmission device (8) and the high-heat-conductivity optical window sheet (6). In addition, one or more semiconductor chilling plates (7) are arranged between the cooling conduction metal piece (1) and the laser heat sink (2), wherein the hot ends of the semiconductor chilling plates (7) are in contact with the laser heat sink (2) and the cold ends of the semiconductor chilling plates (7) are in contact with the cooling conduction metal piece (1). In the above-mentioned high power VCSEL semiconductor laser treatment device, the semiconductor chilling plates (7) and the VCSEL arrays (4) share the heat sink, so that the inner structure is simplified. Therefore, the laser treatment device has the advantages of being simple in structure, powerful in function, easy to manufacture, high in reliability and the like, thus having broad application prospects in the field of laser medicine.L'invention concerne un dispositif de traitement laser VCSEL (laser à cavité verticale et à émission par la surface) haute puissance doté d'une fonction de refroidissement de la peau, comprenant des réseaux VCSEL (4) assemblés sur un dissipateur thermique à laser (2), un dispositif de transmission optique (8) disposé en face des faces de sortie de lumière des réseaux VCSEL (4) et une feuille de fenêtre optique à thermo-conductivité élevée (6) collée à l'extrémité d'un orifice de sortie de lumière du dispositif de transmission optique (8).
