Abstract

An improved experimental setup for measuring picosecond absorption recovery time is reported. Absorption recovery time for cryptocyanine in ethanol is measured to be 16±3ps. Based on simplified two-level model the relaxation time for upper level of the cryptocyainie molecule is estimated to be 21*4ps.
