Abstract

We have developed compact millimeter thick optical fiber arrays with nonlinear optical liquid guiding core. The fiber arrays are capable of high quality image transmission of scenery, while providing protection of the eyes and sensors against frequency agile lasers short pulses [nanosecond-picosecond] in the visible spectrum. In this paper, we present the theoretical model for the various linear and nonlinear absorption processes and nonlinear propagation of short laser pulses in the constituent fiber cores. We also discuss how a recently discovered extremely nonlinear response of nematic liquid crystal film may be employed for limiting action on longer pulse or cw lasers with nanowatt threshold power.
