The finite-element method has been used in a program for numerical solution of the equations describing laser self-focussing in the isotropic phase for nematic liquid crystals. It is shown that the spatial dispersion in the nonlinear susceptibility arising from the thermal and orientation mechanisms stabilizes the time envelope of the laser pulse, while sharpening the leading edge and reducing the characteristic selff ocussing length.
