Paper Abstract

Phase-matched difference-mixing of the frequency tunable CO2 lasers in three nonlinear crystals is considered to generate a tunable submillimeter radiation. Optical properties of ZnGeP2, AgGaSe2, and new promising nonlinear mixed crystals like AgGaxIn1-xSe2 in middle IR and FIR spectral ranges have been investigated. The coefficients of Sellmeier dispersion equations for AgGaxIn1-xSe2 and AgGaSe2 for IR and those for ZnGeP2 for FIR have been determined. Phase- matching curves and phase-matching angular widths for both direct and backward waves have been calculated. A principle possibility of application of the emission converted is shown to control some atmospheric pollutants.
