Paper Abstract

The dual frequency Amplified Spontaneous Emission (ASE) bands observed in certain aminocoumarin dyes under nitrogen laser excitation were explained as due to the planar and the twisted intra molecular charge transfer (TILT) con- formations of the dye in the excited state. This paper presents a study of small signal laser gain of aminocoumarins with different substitutions in a variety of organic sol- vents.
