Abstract
An arrangement ( ) for efficiently generating tunable pulsed laser output at 8-12 microns. The arrangement ( ) includes a laser ( ), a first optical parametric oscillator ( ) of unique design, and a second optical parametric oscillator ( ). The first oscillator ( ) is constructed with an energy shifting crystal ( ) and first and second reflective elements ( ) and ( ) disposed on either side thereof. Energy from the laser ( ) at a first wavelength is shifted by the crystal and output at a second wavelength. The second wavelength results from a secondary process induced by a primary emission of energy at a third wavelength, the third wavelength resulting from a primary process generated from the first wavelength in the crystal. Mirror coatings are applied on the reflective elements ( and/or ) for containing the primary emission and enhancing the secondary process. The second optical parametric oscillator ( ) then shifts the energy output by the first OPO ( ) at the second wavelength to the desired fourth wavelength.
