Abstract

Nonlinear optical transmission in single Cd_0.2Hg_0.8Te crystals in the range of fundamental absorption at high laser intensity level was investigated at 298K. For thick samples the decease of light transmission up to five times was registered at wavelength length (lambda) equals 10.6 micrometers and at laser intensity level 300 kW/cm². It was explained by new channel of absorption: two-level transition of the electron inter-intra-band increase under the laser pulse influence.
