We present a critical account of intense pulsed-laser field induced refractive index changes caused by flow, crystalline axis reorientation and distortion and other high order photonic processes in transparent liquid crystals. In particular, the optical nonlinearity associated with Maxwell Stress induced flow-reorientation in nematic liquid crystals is explicitly calculated, and their possibility for all-optical switching application is experimentally demonstrated. Similar flows processes have also been observed in Blue-Phase liquid crystals with nanosecond and picosecond pulsed-lasers.
