HIGH EFFICIENT SURFACE EMITTING LASER DEVICE, LASER PUMPING UNIT FOR THE LASER DEVICE AND METHOD FOR FABRICATING THE LASER PUMPING UNIT

摘要

Provided are a VECSEL device, which improves optical pumping efficiency by including a mirror reflecting an optical pumping beam, and a method of manufacturing the same. The device includes a lase-pumping unit emitting light having a predetermined wavelength; and a pump laser providing an optical pumping laser beam to the laser-pumping unit. Herein, the laser-pumping unit includes an active layer absorbing the optical pumping laser beam to emit light having a predetermined wavelength; a first reflector reflecting the light emitted from the active layer; and a second reflector reflecting the optical pumping laser beam, which are not absorbed in the active layer but transmit the first reflector, toward the active layer.
