Patent ID: 7653113

Claim:
A vertical external cavity surface emitting laser (VECSEL) cavity surface, comprising: a surface emitting laser unit including a first active layer having a multiple quantum well structure emitting light having a first wavelength, a reflective layer on a surface of the first active layer, and a first mirror opposite to a surface of the first active layer and defining a first cavity resonator together with the reflective layer; at least one pump laser unit located on an upper surface of the surface emitting laser unit, the at least one pump laser unit having a perpendicular light emissive surface and a second cavity resonator perpendicular to the first cavity resonator; and a beam reflector configured to reflect a light having a second wavelength emitted from the pump laser unit toward the surface emitting laser unit, wherein the beam reflector is formed on the perpendicular light emissive surface of the pump laser unit so as to have an inner reflecting surface in contact with the perpendicular light emissive surface and a concavely curved outer reflecting surface located outside of the first and second cavity resonators.
