Paper Abstract

Optimum condition for the lasing efficiency of four organic compound, as an active laser medium, excited by a Nytrogen pulsed laser (FWHM ? 5.7ns), has been investigated. The output energy was dependent on: solvent, dye concentration and for three of the compounds (II, III and IV), of protons concentration in the solvent used. We show lasing efficiencies in table I. According to the obtained results, we have specially discussed the importance of protons in photoinduced charge transfer process, in the compounds with an amino terminal group in the substituent R1.
