ABSTRACT:
A laser apparatus capable of emitting a laser beam upon wavelength conversion and intensity modulation, which comprises a fundamental wave resonance means comprising a light emitting part, an optical resonator comprising mirrors sandwiching the light emitting part and capable of laser resonating, and a modulation-conversion means set inside said optical resonator, said light emitting part being a semiconductor light emitting element or a laser medium, said modulation-conversion means converting, by a nonlinear optical effect, a fundamental laser resonance wavelength light, and phase modulating said light by an electro-optical effect, and a modulation part of said modulation-conversion means comprising electrodes for application of a modulation voltage. The laser apparatus of the present invention is compact and has a simple structure as compared to conventional ones, but it is capable of wavelength conversion of the fundamental wave beam by SHG and intensity modulation of this SHG laser beam at a high modulation degree with a low modulation voltage, and emission of the light. The method of use thereof is also very simple and can fulfill the need of a laser apparatus which serves well as a light source for optical communication and the like.
