Abstract
An arrangement ( ) for efficiently shifting energy received at a first wavelength and outputting the shifted energy at a second wavelength. The arrangement ( ) includes a laser ( ) and an optical parametric oscillator ( ) of unique design. The oscillator ( ) is constructed with an energy shifting crystal ( ) and first and second reflective elements ( ) and ( ) disposed on either side thereof. Light from the laser ( ) at a fundamental frequency is shifted by the crystal and output at a second wavelength. The second wavelength is a secondary emission of energy induced by a primary emission generated by the first wavelength in the crystal. A novel feature of the invention is a coating applied on the reflective elements ( and/or ) for containing the primary emission and enhancing the secondary emission. This constrains the energy to be output by the arrangement ( ) at the wavelength of the desired secondary emission.
