ABSTRACT:
A short-wavelength laser light source having a semiconductor laser for emitting laser light is provided. The light source includes a power supply for driving the semiconductor laser and thereby causing the semiconductor laser to emit a fundamental wave, a polarization inversion-type light-wavelength converting device for generating from the fundamental wave a harmonic wave having a shorter wavelength than the fundamental wave; and laser light feedback means for feeding light of the fundamental wave lying in a selected wavelength region back to the semiconductor laser, thereby achieving oscillation wavelength locking. Said power supply supplies to the semiconductor laser a high-frequency power containing AC components oscillating in a cycle short enough to cause the semiconductor laser to emit the fundamental wave in the form of pulsed laser light.
