Abstract
A solid-state tunable laser having a ND:YAG pumping source, a chromium-doped fosterite crystal lasing medium, a birefringent filter for selecting a specific fundamental wavelength, a pair of harmonic generating crystals mounted on counter-rotating platforms driven by stepper motors under the control of a computer, a partially reflective, partially transmissive mirror for directing the output of the pumping source through the lasing medium so that the lasing medium produces radiation having a range of fundamental wavelengths, and a fully reflective mirror for directing the radiation of the specific fundamental wavelength through the birefringent filter and the pair of crystals so as to produce radiation of a harmonic wavelength of the specific fundamental wavelength.
