Abstract
According to the present invention, a laser light source comprises plural semiconductor lasers (), a solid laser (), a non-linear material () as a wavelength conversion element, a reflection coat () formed on one facet of the solid laser, and a reflection coat () formed on one facet of the non-linear material (), and the solid laser and the wavelength conversion element are disposed between the both reflection coats to constitute a laser resonator, and plural pump parts () in the solid laser () which are pumped by the plural semiconductor lasers are separated from each other by 300 μm or more. Thereby, interference between transverse modes of laser oscillation is avoided, thereby providing a high-power, stable, and compact solid laser light source with which a stable high output power can be obtained.
