Abstract
An optical frequency mixer according to one embodiment of the present invention comprises a V-shaped resonant cavity including a first reflective surface, a second reflective surface and an output coupler, a pumping unit configured to emit a pumping wave to the laser gain medium to generate a resonating wave in the resonant cavity, a nonlinear crystal positioned on an optical path of the resonating wave in the resonant cavity, and an input interface configured to emit a mixing wave into the resonant cavity. Preferably, the output coupler can be a plano-concave lens having a concave surface configured to reflect the resonating wave and to focus the resonating wave such that the spot size of the resonating wave is matched the spot size of the pumping wave. Particularly, the nonlinear crystal is positioned between the output coupler and the input interface.
