We report the observation of nematic-to-isotropic transition induced by two-photon absorption in azobenzene liquid crystals. Optical Kerr effect was used to monitor the transition through the pump–probe scheme, and the pump threshold for the transition showed the expected dependence on pump energy per pulse. Qualitatively different behaviors of the transitions induced one- and two-photon excitations were observed.
