Abstract:
A device for the nonlinear combination of laser light comprising:a) a tunable fiber laser light source which produces a first energy beam along an optical path at a given frequency, wavelength, and intensity and includes thermal and piezoelectric elements for providing variable adjustment to at least the frequency of the first energy beam; b) a nonlinear resonator placed in the optical path of the first energy beam; c) a nonlinear optical crystal disposed in the optical path of the first energy beam within the nonlinear resonator for converting the frequency of the first energy beam; and d) a feedback system operatively connected to the nonlinear resonator and the thermal and piezoelectric elements of the fiber laser light source, said feedback system being configured to adjust the frequency of the laser light source to match resonant frequency conditions within the nonlinear resonator.
