Fatty acids and cholesterol are important substances for the living matter, especially for the biological membrane [1]. Since the liquid crystal state of these substances can give information on some membrane mechanism [2], their answer to some external stimuli within the mesomorphism interval has been widely studied. The possibility of inducing a non-linearity in such systems could lead to a radical change of their dynamics. Interesting non-linear optical laser based answers were obtained in different thin film samples. We analyzed these effect answers and the measurement procedures. For simulating the generation of delayed pulses inside organic mixtures a mathematical model based on practical test-functions has been used. The input pulse (usually represented by an optical or electromagnetic pulse) generates a delayed pulse inside the material medium, and thus a modulated input pulse represented by a gaussian function modulated by a sine function has been used for simulation, with good results.
