Abstract
Provided is a laser oscillation apparatus capable of stabilizing resonance even when finesse of an optical resonator is increased and generating stronger laser light than that of a traditional apparatus by accumulating laser light in the optical resonator. The laser oscillation apparatus includes a laser light source which generates laser light for excitation, a fiber amplifier which generates laser light with a desired wavelength when the laser light generated at the laser light source for excitation is supplied, an optical resonator, an optical isolator which is interposed between the optical resonator and the fiber amplifier and which guides the laser light from the fiber amplifier to one side of the optical resonator while blocking laser light in the opposite direction, a circulation optical path which accelerates resonance as introducing laser light emitted from the other side of the optical resonator and returning the laser light to the optical resonator via the fiber amplifier and the optical isolator, and a modulator which performs amplitude modulation on the laser light in the circulation optical path.
