Abstract

Recent advances in the synthesis of novel strongly fluorescing laser dyes have renewed interest in dye-laser technology The pyrromethene-BF₂ complex (PM) family of dye molecules have a laser performance that is superior that of rhodamine dyes in both liquids¹ and solids.² BASF perylimide dyes also exhibit reasonable laser efficiencies and stabilities.³ The purpose of this study is twofold: (1) to test the compatibility of four new PM dyes and two BASF perylimide laser dyes in a high-temperature plastic (HTP) and (2) to compare the laser performance (slope efficiencies and lifetimes) of the PM dyes to that of the perylimide dyes under 532-nm end-pumped conditions.²
