Picosecond kinetics of IR reflection and transmission in highly excited II-VI crystals
Kuokshtis E. , Crus J. , van Driel H. M.
The time evolution of the reflection and transmission of picosecond light pulses at a wavelength λ = 2.8 μνα in single crystals of CdSe and CdS^ _ x $qx excited by an intense pulse of a strongly absorbed light is studied. A competition among several mechanisms for the modulation of a complex refractive index of a substance is found to exist.
