Pi. Khadzhi et Lv. Fedorov, Characteristic features of the interaction of ultrashort resonant laser radiation pulses with thin semiconductor films, QUANTUM EL, 29(10), 1999, pp. 899-903
The relationships governing nonlinear transient transmission and reflection
of ultrashort resonant laser radiation pulses with rectangular and Gaussia
n profiles by a thin semiconductor film were investigated taking into accou
nt the exciton-photon interaction and the concentration enhancement of the
dipole moment of the exciton transition. It is shown that the transmission
of a Gaussian pulse is characterised by the formation of two subpulses with
identical areas, which are separated in time and have different profiles.
