This review compiles the work performed in the field of organic solid-state lasers with the hole-transporting organic molecule N,-bis(3-methylphenyl)-N,-diphenylbenzidine system (TPD), in view of improving active laser material properties. The optimization of the amplified spontaneous emission characteristics, i.e., threshold, linewidth, emission wavelength and photostability, of polystyrene films doped with TPD in waveguide configuration has been achieved by investigating the influence of several materials parameters such as film thickness and TPD concentration. In addition, the influence in the emission properties of the inclusion of a second-order distributed feedback grating in the substrate is discussed.
Keywords: N,N´-bis(3-methylphenyl)-N,N´-diphenylbenzidine system (TPD); lasers; amplified spontaneous emission N,N´-bis(3-methylphenyl)-N,N´-diphenylbenzidine system (TPD); lasers; amplified spontaneous emission
