    摘要: Provided is a Vertical External Cavity Surface Emitting Laser (VECSEL). The VECSEL includes a semiconductor chip, a pump laser, a narrow bandwidth polarization filter, an external mirror, and a Second Harmonic Generation (SHG) element. The semiconductor chip includes an active layer generating light having a wavelength and a reflective layer reflecting the light generated in the active layer. The pump laser emits a pump beam for exciting the active layer. The narrow bandwidth polarization filter is formed on the semiconductor chip and polarizes the light. The external mirror faces the active layer, amplifies the light emitted from the active layer by repeatedly reflecting the light toward the reflective layer, and outputs the amplified light out of the VECSEL. The SHG element is disposed between the narrow bandwidth polarization filter and the external mirror and converts the wavelength of the light.
