Abstract:
A laser beam source device includes: a first light emission element and a second light emission element each of which has a light emission portion for emitting a laser beam having a fundamental wavelength, wherein the first light emission element and the second light emission element are disposed such that light emitted from the light emission portion of each of the first light emission element and the second light emission element can enter the light emission portion of the other light emission element, at least either the first light emission element or the second light emission element has the plural light emission portions, and the areas of the plural light emission portions are not uniform.
