Abstract:
1. A wavelength conversion laser device, comprising: a laser light source which emits a laser beam; two reflective surfaces which reflect therefrom the laser beam emitted from the laser light source; a wavelength converter which converts the laser beam into a wavelength-converted laser beam, said wavelength converter being provided between said two reflective surfaces; and condensing optics which condense the laser beam emitted from the laser light source to be injected between said two reflective surfaces, wherein at least one of said two reflective surfaces has a curvature for reflecting the laser beam to be re-injected into said wavelength converter between said two reflective surfaces repeatedly while forming multi paths of laser beams injected into said wavelength converter at different incident angles, and said condensing optics are arranged to disperse beam waists of the laser beams in said wavelength converter, which reciprocate between said two reflective surfaces.
