ABSTRACT:
A wavelength selecting optical element such as a narrow band-pass filter or the like is provided between a semiconductor laser and a light wavelength conversion element formed of a bulk-shaped wavelength conversion crystal. The wavelength selecting optical element selects a wavelength of a laser beam which is to be reflected by an end surface of the light wavelength conversion element to be fed back to the semiconductor laser.
