ABSTRACT:
A vertical external cavity surface emitting laser is provided that is integrally mounted on a single heat sink together with a pump laser. In the surface emitting laser, a laser chip has a gain structure to emit light at a predetermined wavelength and it is disposed on a center portion of a top surface of a heat sink, an external mirror is spaced apart from the laser chip at a predetermined distance to transmit a portion of the light emitted from the laser chip to an outside and to reflect the remaining portion of the light to the laser chip, a pump laser is disposed on one side of a top surface of the heat sink to emit pump light in a horizontal direction for activating the laser chip, and a reflection mirror is disposed on the other side of the top surface of the heat sink opposite to the pump laser to reflect the pump light emitted from the pump laser to the laser chip.
