Le champ optique d'un laser continu est assez fort pour induire un grand changement de l'indice de réfraction d'un cristal liquide. La transition structurelle induite par un champ optique peut avoir lieu. La grande nonlinearité optique peut mener à des phénomènes d'optique nonlinéaire intéressants.CW laser fields are strong enough to induce a large refractive index change in a liquid crystal. Optical-field-induced structural transition can occur. The large optical nonlinearity can lead to some unusual highly nonlinear optical phenomena
