Laser Dye Synthesis - Group C Compounds
Abstract
This report describes progress on the syntheses of a number of new potential laser dyes. The goal is to generate new structures allowing the upscaling of flashlamp pumped dye lasers to high energies. These systems ideally should show a lower laser action threshold, operate with high efficiencies, and exhibit greater photochemical stabilities than do those presently available. Pavlopoulos has proposed a) that the parent aromatic chromophores be substituted by auxochromic groups such as hydroxy, alkoxy, and dialkylamino and b) that improvement should result by restricting the chromophore and auxochromic group to coplanarity. This should reduce intersystem crossing and thus improve the quantum fluorescence yield. The potential dye lasers described below are designed to meet these objectives. Keywords: Ethylene, Dimethylfluorenes.
