Abstract
There is provided a harmonic generator generates high power laser light and can be modulated at high modulation rate. The semiconductor laser emits a first output light when a bias current is supplied, and a second output light when a modulating current is superposed to the bias current. On of the first output lights has a wavelength inside of a wavelength tolerance of phase-matching of the wavelength-converting element. The other has a wavelength outside of the wavelength tolerance of phase-matching.
