    The molecular nonlinear photonic absorption processes of two nonlinear fiber core liquids are discussed in the context of nonlinear propagation and optical limiting of short pulses, these fiber arrays are capable of limiting threshold and clamped output below 1 μJ for picosecond and nanosecond pulses. We also discuss the observation of perhaps the largest optical nonlinearity in some dye-doped nematic liquid crystal films. These films provide limiting action with a threshold power of 100 nWatt and limited transmission of ≪1 microJoule for ms-CW laser
