Abstract

Experimental results of measurements of the threshold power density of stimulated radiation in solutions of the coumarin-30 dye with ZnO nanoparticles irradiated with femtosecond laser pulses are presented. It is shown that the thresholds of stimulated emission in solutions of the coumarin-30 dye with ZnO nanoparticles are approximately three orders of magnitude higher than the thresholds of stimulated emission in solutions of the coumarin-30 dye with ZnO nanoparticles irradiated with nanosecond laser pulses.
