The report summarizes research in which the authors have examined the time development of the various frequencies in a grating-tuned, flash-pumped dye solution laser and interpreted these in terms of a four-state kinetic model that they have previously used with success for a description of molecular gas lasers. One of the significant parameters in the description of this model is the extent and nature of the homogeneous broadening in the dye molecule, and they have investigated this aspect by studying the temperature and solvent state dependence of dye absorption and emission spectra. Radiative lifetimes and self-quenching cross sections have been determined for glyoxyl and iodine monochloride using tuned laster pulses. Another promising application of the dye laser is in detection of trace quantities of such contaminants as NO2 in the atmosphere. Detection limits for such a monitoring system have been estimated.
