Abstract
A laser light source device includes: a first light emitter that emits a first laser beam; a second light emitter that emits a second laser beam; an optical element that converges the first laser beam and the second laser beam; a wavelength dispersing element on which the first laser beam and the second laser beam from the optical element are incident, and which causes optical axes of the first laser beam and the second laser beam to coincide with one another, and then transmits the first laser beam and the second laser beam; and a partially reflecting mirror that returns portions of the first laser beam and the second laser beam from the wavelength dispersing element by reflection, and transmits remaining portions of the first laser beam and the second laser beam that have exited from the wavelength dispersing element. The reflectance of the partially reflecting mirror is wavelength-dependent.
