Advanced Excitation Techniques for Tunable Infrared Lasers.

Abstract

This report describes the theoretical concept and experimental progress initiated to devise a tunable laser source, broadly tunable over the middle infrared wavelength range. The concept derives from frequency conversion by scattering from coherently driven Raman vibrations in hydrogen or methane gas. This investigation concentrated on the feasibility of producing a wide-band tunable, infrared source using a designator energy category Nd:YAG pump laser to simultaneously drive a lithium niobate parametric oscillator and coherent Raman mixing in gaseous media.
