Abstract

Optimal control theory is applied to design a laser pulse to produce an anisotropic change of the refraction index in the vicinity of the isotropicnematic phase transition in liquid crystals. The laser induced birefringence originates from the orientational anisotropy induced by the laser field that is enhanced significantly due to the excluded volume effect. The shape of the optimal pulse is analyzed for different values of relaxation time and different molecule concentrations.
