Nonlinear acoustooptic spectroscopy of atmospheric gases
Abstract
Results on the nonlinear acoustooptic spectroscopy (AOS) of molecular gases in the visible and IR ranges are summarized. Particular consideration is given to the principles of AOS operation, pulse shaping in AOS under pulsed excitation for both low and high radiation intensities, and the relationship between the AOS signal and parameters of saturated absorption line profiles. An experimental nonlinear AOS technique is described which employs three lasers: ruby at 0.69 micron, Nd:glass at 1.06 micron, and CO2 at 10.6 microns. Future prospects relating to the development of this method for the nonlinear V-R spectroscopy of molecules are discussed.
