Transient and steady-state multi-wave mixing experiments are carried out on the novel azoc-tube liquid crystal sample. The shape of the diffracted multi-wave consists of rings under Ar514.5nm laser pump light, and th e nonlinear refractive index is n0.8. Using different polarization states of the pump laser light field, different reorientation models of liquid crystal molecules ar e observed. On the other hand, a Nd:YAG532nmpulsed laser is used, polarizati on holographic gratings are detected by a He-Ne (632.8nm)laser beam. Different p rocesses of liquid crystal molecular reorientation are also detected using the o -light beam and e-light beam of a He-Ne (632.8nm)laser.
