Abstract

Coumarin 540-A has been dissolved in a copolymer of 2-hydroxyethyl methacrylate (HEMA) and methyl methacrylate (MMA) 1:1 v/v and in a pure poly(methyl methacrylate) homopolymer (PMMA). Laser action has been induced in the resulting solid-state solutions pumped with 1.2 mJ pulses at 337 nm from a nitrogen laser. The effects on the laser performance of different polymerization methods, dye concentration and polymeric matrix composition have been evaluated. Energy conversion efficiencies of 11% and lifetimes of about 2000 pulses at 2 Hz repetition rate have been demonstrated.
