Abstract
A laser source device provided with a light source, a wavelength conversion element, an external resonator, and an optical path conversion element. The wavelength conversion element is disposed inside the resonance structure, the second laser beam is taken out on the second optical path by the optical path conversion element and is led to a direction substantially the same as the proceeding direction of the first laser beam, and is used with the first laser beam as the output light beam. The selectively reflective film and the reflective surface for taking out the second laser beam are integrated.
