Abstract:
A wavelength conversion laser light source, includes: a solid laser medium; a wavelength conversion element; a concave mirror on which a first reflecting surface reflecting a fundamental light wave and a the second harmonic light wave is formed; and a wavelength plate on which a second reflecting surface reflecting the fundamental light wave and transmitting the second harmonic light wave is formed, wherein a laser resonator is constituted by the first reflecting surface and the second reflecting surface; the solid laser medium is arranged on a first reflecting surface side of the laser resonator, the wavelength plate is arranged on a second reflecting surface side of the laser resonator, and the wavelength conversion element is arranged between the solid laser medium and the wavelength plate; and the wavelength plate outputs the second harmonic wave, to the exterior of the laser resonator, via the second reflecting surface.
