Abstract
The results of theoretical and experimental studies of the possibility to use semiconductor quantum-well lasers, operating in the autodyne regime, for creating nanovibration and nanodisplacement meters are presented. The specific features of the autodyne signal formation under the conditions of strong and weak optical feedback, the influence of current modulation on the shape and spectrum of the autodyne signal, and the methods of measuring the parameters of micro- and nanomotions are described. The description of methods and instrumentation using laser autodynes for the analysis of nanovibration and nanodisplacement parameters of biological objects is presented.
