DYNAMIC AND STEADY-STATE BEHAVIORS OF REVERSE SATURABLE ABSORPTION INMETALLOPHTHALOCYANINE

The dynamic and steady-state processes of the reverse saturable absorp tion (RSA) and the related optical limiting (OL) and optical bistabili ty (OB) in metallophthalocyanine have been studied in detail using rat e equations and the light-propagation equation. The experiments for de monstrating RSA, OL, and OB in a copper phthalocyanine (CuPc) solution with a e-switched, frequency-doubled neodymium-doped yttrium-aluminum -garnet (Nd:YAG) laser were accomplished. The experimental results wer e consistent with the dynamic theoretical simulations, also approximat ely in accordance with the expression of RSA derived from the same equ ations at the steady-state condition.
