Paper Abstract

Using nematic liquid crystal films doped with photocharge producing dyes, we have demonstrated the feasibility of optical limiting of long pulse - cw lasers at nanowatt power, and clamped transmission of < < 1(mu) J. We also demonstration incoherent-coherent image conversion capability with optical intensity in the (mu) Watt/cm2 level.
