ABSTRACT:
A second harmonic generator has a semiconductor laser for a fundamental wave light source. The laser includes a semiconductor laser chip and a quasi-phase matching element optically coupled together in series. The semiconductor laser chip can lase utilizing feedback of a light from the quasi-phase matching element. The quasi-phase matching element receives a laser emitted from the semiconductor laser chip and generates a second harmonic light using the laser beam as a fundamental wave light.
