Author Affiliations +
For the first time three-wave interaction of picosecond pulses was investigated as difference frequency generation with Ag- GaSe2 crystal. Group velocities and radiation absorption were taken into account during spectral analysis realization. Calculations were executed for CO2 laser parameters: 100 divided by 5 ps, 15 divided by 150 GW/cm2. Spectral characteristics and pulse power versus crystal length are represented for difference wavelength 800.5 micrometer.
