Concentration and Dye Length Dependence of Organic Dye Laser Spectra

Abstract

Experimental data comparing peak emission wavelength with organic dye laser cell length are presented. These data and knowledge of the variation of peak emission wavelength with organic dye concentration make reasonable the hypothesis that the observed effects are caused by self-absorption. A simple theory is developed on this hypothesis and the results of numerical calculations compared with the experimental data. Good agreement is obtained, but some departures from agreement suggest improvement may be expected from a time-dependent theory.
