AbstractThe scattering properties of polymer dispersed liquid crystal (PDLC) composites are studied and applied to optically addressed devices for the protection against continuous wave laser. The geometry of the device is chosen with respect to its scattering efficiency, linear transmission and response time. The optical limiting performances of this PDLC-based device are measured at 514 nm.

We present our results on nonlinear optical (NLO) of chicago sky blue 6B doped polyvinyl alcohol (PVA) film. This film was studied at 633 nm and 532 nm using a continuous wave laser. We have evaluated the sign and magnitude of the third-order nonlinearity from the closed aperture Z-scan data while the nonlinear absorption properties were assessed using the open aperture data. The chicago sky blue 6B doped PVA film exhibited nonlinear saturated absorption and strong self-defocusing effect. The limiting effect of the sample was studied and the results indicate that the film possesses good characteristic of optical limiting.
