Abstract:

The spectrum formation of difference frequency generation between CO2 and CO lasers radiation is theoretically and experimentally studied in an AgGaSe2 crystal at I type phase matching. The study shows a promise of this crystal for developing selective laser sources tunable in the wavelength range 12–16.6 microns. Phase-matching angles for difference frequency generation between CO and CO2 lasers radiation were measured and compared with those calculated by various dispersion equations. The combination of dispersion equations, which describes the difference frequency generation in the wavelength range 12–16.6 μm the most correctly, was chosen.

Keywords:

mid-IR range, molecular gas lasers, difference frequency generation, nonlinear crystal
