Abstract
A laser light source is provided with a pump light source () comprising a semiconductor laser, a solid laser medium () which is excited by the semiconductor laser, and multi-mode means for changing at least either a longitudinal mode or a transverse mode of laser oscillation of the solid laser. The oscillation light of the laser medium excited by the light outputted from the pump light source is changed by the multi-mode means into output light () having a plurality of oscillation spectra and is outputted, thereby a small, high power, and highly efficient low coherent light source can be realized, and a laser light source having reduced speckle noises can be provided.
