Bichromatic operation of a pulsed solid state dye laser

摘要

Abstract: Dye doped polymeric solid samples of prismatic form and high optical quality were pumped by a short-pulse nitrogen laser. No external resonator or dispersive intracavity elements were added. For rather critical pumping conditions the usual narrow band laser spectrum bifurcates to a bichromatic one. A simple model of rate equations accounts for the main experimental results. !7
