✦ Synopsis

Picosecond absorpGm and gain spawa of ~dicrhylamin~-nilroslilbenc (DEANS) were measured wiih a mode-locked Nd:YAG laser. The largcs~ gain ever reponed (1.1 X103 cm-') was obtained by a DEANS (0.7 mol dm-") doped polymer film. The S, -* S,, gain of DEANS (1.2x lo-' mol dm -3) in benzene decreases with Ihe photon tlwt of the probe light from 6 x Ib" to 3 x 10" phoIons/cm' s in khe X30-680 nm region.
