Abstract

A ∼13% increase in the absorption coefficient is seen by a weak probe beam to build-up exponentially in ∼50 ps and decay in ∼1.4 ns after a ∼30 ps intense pump pulse (∼220 mJ/cm2 ) at 532 nm goes through a bis-benzothiazole/H2SO4 solution. We propose a three-level model to explain the effect and obtain the basic parameters by fitting our data to the model.
