We study theoretically the nonlinear optical response of a mono-layer of three-level quantum emitters with a doublet in the excited state. It is shown that the layer’s response exhibits multistability. In a certain frequency range, the monolayer operates as a perfect bistable mirror.

Nonlinear optical response and reverse saturable absorption behavior of various rare earth phthalocyanines such as Nd , Eu , Sm and La in dimethyl formamide (DMF) solution were studied under high power Nd:YAG laser excitation. Excited state absorption cross-sections and two-photon absorption cross-sections of these systems are measured from the limiting characteristics. The SmHPc 2 system yields maximum value for excited state absorption cross-section and its potential application in DMF as a suitable optical limiter is also discussed.
