Using micro-capillaries and capillary arrays, we have fabricated dye- and C60-doped liquid crystal cored fibers and image transmission plates of various core diameters and lengths. We have observed nonlinear pulse propagation and limiting effect using nanosecond 0.53 μm Nd:Yag laser. Typical threshold fluence s on the order of < 1 J/cm2 in a 7 mm long fiber. A theoretical modelling of the observed effect is also presented.
