Abstract

The theory of absorption of femtosecond light pulses due to indirect interband transitions in crystals is developed. The absorption occurs due to two-quantum processes with participation of a photon and a phonon. Expressions governing J, the density of energy absorbed during the laser pulse action, and its dependence on laser pulse duration, temperature, and frequency of light are obtained.
