Resonant Raman scattering of light in anthracene crystals
Broude V.I., Maksimov A.A., Tartakovskii I.I.
Excitation of anthracene crystals (Γ = 4.2-30 К) by a tunable dye laser near the bottom of the lowest exciton band (v0 = 25097 cm'1) has revealed a sharp increase in intensity of the Raman scattering (RS) of light, and no less sharp a decrease of its intensity in the immediate vicinity of the resonance. The RS intensity was found to be extremely sensitive to the intensity of the exciting light and to the crystal temperature. The results are discussed within the framework of the concept of stimulated resonant Raman scattering of light.
