Description

The melting thresholds Wm = 40-50 mJ/cm2 at initial temperature T0 100 K and Wm = 30-40 mJ/cm2 at T0 = 300 K were determined by a numerical simulation of the process of nanosecond ruby laser pulsed irradiation of Cd0.2 Hg0.8 Te. Laser-induced modification of the sample surface under irradiation with energy W < Wm that resulted in a stationary photoconductivity quenching and a rise of the reflection coefficient was found. Laser treatment with W above the melting thresholds caused the additional increase of the reflection coefficient at Wm < 100 mJ/cm2 and its drop at Wm > 110 mJ/cm2
