Abstract
Non linear optical response and reverse saturable absorption behavior of various rare earth phthalocyanines such as Nd, Eu, Sm and La in di-methyl formamide (DMF) solution were studied under high power Nd:YAG laser excitation. The size of the central metal atom of the Pc ring is found to considerably affect the nonlinear response of these systems. Excited state absorption cross sections of these systems are measured from the limiting characteristics. The SmHPc2 system yields maximum value for absorption cross-section and its potential application in DMF as a suitable optical limiter is also discussed.
