Investigation of ultrasonic action effects in quantum heterolasers.

The influence of alternating strains on the spectral characteristics of the radiation of quantum-dimensional heterolasers is studied experimentally and theoretically. A brief review of the previously obtained results of the study of the deformation effect on the frequency spectrum of radiation is presented. A detailed analysis of the results obtained recently in the study of the influence of ultrasonic strain on the polarization properties of laser structures of various compositions is carried out. An anomalously large effect of rotation of polarization by ultrasonic strain has been found in laser structures on quantum dots.
