摘要：

A detailed study was conducted for two-photon absorption of a selected group of new derivatives of cyclohexanone/piperidone with regard to their molecular structure and the feasibility of using these derivatives as nonlinear optical absorbers for optical limiting. Derivatives of cyclohexanone/piperidone have a cross-section of two-photon absorption of the order of 3000 x 10(-50) cm(4)s/photon and compare well against known two-photon absorbers. This makes them promising nonlinear optical absorbers and optical limiters. Their important feature is that the energy is absorbed in the infrared region, where the protection is needed for remote IR sensors and night-vision systems. It is also important that the energy of the dissipated infrared radiation is converted mostly into fluorescence but not into heat that can damage optical limiter.
