Orientational self-bleaching for pulsed dye lasers with polarized pumping

摘要

The dynamics of pulsed pumped dye lasers with transversal excitation geometry with linearly polarized pumping when the absorption dipole is perpendicular to the emission dipole have been theoretically and experimentally investigated. The theoretical model is based on balance equations and takes orientational relaxation processes into account. Experimental results have been obtained on Rhodamine 6G in Ethyleneglycol under pulsed transversal polarized pumping from a N$-2$/ laser. The theoretical and experimental results obtained allow us to call the new effect: orientational self-bleaching.
