Abstract

Fluorescence characteristics of 2-(4-pyridyl)-5phenyloxazole (4PyPO) and trans-stilbene has been studied under high power XeCl laser excitation. Anomal fluorescence phenomenon has been found. Gain and losses were measured in 4PyPO active media in range of excitation rate from 10²³ to 10²⁶ phot/cm²s. Dynamics of losses in laser pulses in coumarine substituted was studied under XeCl laser pumping.
