Nonlinear aspects of relaxation in mode-locking dyes: DODCI

Relationships between photobleaching recovery times and excited state lifetimes for mode-locking dyes are treated. It is shown that under appropriate excitation conditions the recovery time may be substantially shorter than the lifetime of the excited state, in agreement with results which have been...

Description
Summary:Relationships between photobleaching recovery times and excited state lifetimes for mode-locking dyes are treated. It is shown that under appropriate excitation conditions the recovery time may be substantially shorter than the lifetime of the excited state, in agreement with results which have been reported for DODCI. The existence of a two component decay is consistent with a self-dumping mechanism operative at high power densities. Proposed production of a DODCI photoisomer is examined with respect to nonlinear effects present during intense pulse excitation.
