Patent ID: 7447243

Claim:
A laser emitting module comprising: a resonator including 1) a solid-state laser medium, 2) a non-linear optical element for converting a wavelength of light emitted from the solid-state laser medium, and 3) a pair of resonance reflectors disposed in such a way that the solid-state laser medium and the non-linear optical element are positioned in between the resonance reflectors for reciprocating the light therebetween; a laser diode for emitting light for exciting the solid-state laser medium; a window cap having 1) a window section for outputting a light emitted from the resonator therethrough and accommodating the resonator and the laser diode, 2) a split reflector for reflecting a part of a light emitted from the resonator, and 3) a received photo detector for detecting a light reflected by the split reflector; and an optical filter for selecting a wavelength of light emitted from the resonator, wherein, the surface of the optical filter is used as the split reflector.
