Calculations of Collision-Induced Optical Gain in High-Density Mixtures of D2 or HD with a Buffer Gas

摘要

This report presents the results of calculations of collision-induced optical gain in vibrationally-excited mixtures of deuterium or hydrogen deuteride with a buffer gas. Gains of up to 0.07/cm are predicted for gas mixtures at high pressure and reduced temperature. Significant gain is predicted over a frequency range of approximately 2100/cm to 2700/cm (wavelength range 4.8 to 3.7 micrometers) for D2 mixtures and over the frequency range 2600/cm to 3300/cm(wavelength range 3.8 to 3.0 micrometers) for HD mixtures. These results indicate the feasibility of operation of collision-induced-dipole lasers which are continuously tunable over the above frequency ranges.
