The paper deals with an acousto-electron effect in the nanodimensional laser heterostructures. This is an ultrasonic strain-induced modulation of the hole states in the quantum well of these structures. The effect results in a modulation of the laser emission intensity as well as in a turn of the emission polarization by the sound strain. Theoretical treatment of the experimental data is presented.
