Abstract:
A light source unit comprising:a wavelength converter including at least a pair of reflection means and a non-linear optical crystal device, into which fundamental-wave laser light emitted from one fundamental-wave light source is input to generate second higher-harmonic laser light, or into which fundamental-wave laser light emitted from a plurality of fundamental-wave light sources is input to generate sum-frequency laser light;a modulator for spatially modulating the laser light generated by said wavelength converter; andan optical waveguide for propagating laser light from said modulator to a given optical apparatus,said wavelength converter, said modulator, and said optical waveguide being mechanically separated,wherein vibration isolating means are provided for said wavelength converter, said wavelength converter and said modulator, or said wavelength converter, said modulator and said optical waveguide.
