Study of two-photon excitation spectra of organic compounds absorbing in the UV region

V. A. Babenko, A. A. Sychev

P. N. Lebedev Physical Institute, Russian Academy of Sciences, Moscow
Abstract: A method is proposed for recording two-photon excitation (TPE) spectra of organic compounds with the help of picosecond pulses from a dye laser tunable in the range from 550 to 640 nm. The TPE spectra are obtained for organic scintillators and drugs: paraterphenyl in liquid and solid phases, stilbene single crystal and Streptocid powder, having a one-photon absorption band in the region from 270 to 350 nm. It is shown that the vibronic structure in the TPE spectra of these compounds is independent of their aggregate state and is an individual characteristic of each of the compounds.
