Abstract
A novel and efficient system and method for providing an output beam of collimated energy in the 8-12 micron range. The solid state system includes a pump laser (210) for providing an input beam and an OPO (250) using an x-cut potassium titanyl arsenate crystal for shifting the input beam from the first wavelength to a second wavelength. A second optical parametric oscillator (271) is included for shifting the beam from a second wavelength to a third wavelength. The second optical parametric oscillator (271) uses a cadmium selenide crystal. A tuning mechanism with an associated controller is provided to tune the oscillator as needed for a particular application.
Claims8
A solid state laser comprising:
- a first laser for providing an input beam at one micron;
- an optical parametric oscillator with an X-cut potassium titanyl arsenate crystal for shifting said input beam from one micron to 2.59 microns, to provide a 2.59 micron beam;
- and
- an optical parametric oscillator with a cadmium-selenide crystal for shifting said 2.59 micron beam from 2.59 microns to 8-12 microns.
