A quantitative discussion of the laser-heating-induced self-phase modulation in nematic liquid crystals is given. The process of the laser-heating-induced nematic–isotropic transition is analyzed. The intrinsic optical bistability due to the nematic–isotropic phase transition is observed and analyzed.
