Abstract
A nonlinear optical device having a yttrium-aluminum-garnet or yttrium-lithium-fluoride laser rod for producing radiation of a fundamental wavelength, a first mirror located in front of the laser rod along the longitudinal axis of the laser rod reflective of the radiation of the fundamental wavelength but transmissive of radiation of a desired harmonic wavelength, a second mirror located to the rear of the laser rod along the longitudinal axis of the laser rod reflective of radiation of the fundamental wavelength, a phase matched crystal harmonic wavelength generator mounted on a movable platform driven by a motor arranged between the front mirror and the laser rod responsive to radiation of the fundamental wavelength for generating radiation of the desired harmonic wavelength, an output sensor arranged in front of the first mirror for generating a signal indicative of the output power of the laser rod, a beamsplitter for directing a portion of the laser rod output power to the output sensor and a computer for receiving the signal generated by the output sensor and controlling the platform to tune the phase matched crystal in response to the signal.
