    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 μJ. We also demonstration incoherent-coherent image conversion capability with optical intensity in the μWatt/cm2 level
