Abstract
An experimental investigation was made of the dependence of the effici ency eta of self-diffraction of picosecond (approximately 20 ps) light pulses on their frequency offset OMEGA in ultrathin (6-30 nm) narrow- gap PbTe semiconductor films. The dependences eta(OMEGA) exhibit compl ex two-photon electron resonances with positions that change radically with the film thickness. The results are interpreted as a manifestati on of the quantum size (quantum well) effect in the course of transiti ons from the light-hole to the heavy-hole band.
