Using the second harmonic of a mode-locked Nd3+laser, we show that the efficient quenching of the S1state in crystal violet (τR< 10-8sec, yet Q < 10-4in ethanol), involves very rapid repopulation of the ground state. The repopulation time exhibits a cube root dependence on solvent viscosity. We argue that our data are best explained by direct internal conversion. We suggest that the class of triphenyl and diphenylmethane dyes should prove to be efficient and versatile bleachable shutters and passive mode-locking elements for laser construction. © 1974.
