Amplified Spontaneous Emission Characteristics of LD 473 and Coumarin 102 Laser Dyes (original) (raw)

Abstract

The amplified spontaneous emission spectrum (ASE) of the laser dyes LD 473 and coumarin 102 in certain solvents is largely red shifted from the fluorescence band maximum. The emission characteristics of these dyes have been studied in various solvents using spectrofluorimeter measurements and laser pumping to understand the above behaviour. The study shows that the photophysical properties of LD 473 and coumarin 102 observed under laser pumping may be different from those observed under conventional spectrofluorimeter measurements.
