Polarization Dependence of Laser-Induced Fluorescence in Anthracene

Abstract
The polarization dependence of double-photon excitation of fluorescence in anthracene has been observed by using a Q-switched laser. It has been found that the fluorescence is a maximum for linearly polarized light and zero for circularly polarized light. The results agree with an earlier interpretation of double-photon excitation transitions between bands having different parity.
