An overview of the program of the laser photo—acoustic spectroscopy development at the Institute of Atmospheric Optics of Siberian Branch of the Russian Academy of Sciences from 1974 to 1994 is presented. Physical basis of the method and specifications of the photo—acoustic spectrometers with pulsed and cw lasers of IR and visible spectral ranges are shown. The main results of fundamental investigations of absorption spectra fine structure and parameters of individual spectral lines of atmospheric molecular gases, nonlinear spectroscopic effects in gases, and measurements of time of vibrational relaxation of high vibrational states in H2O molecule are described. The prospects of development of photo—acoustic spectroscopy instrumentation and its applications to atmospheric study are discussed.
