dc.description.abstract | We report the nonlinear absorption and refraction of banana shaped liquid crystal, namely 1,3-phynelyne bis [N-(2-hydroxy-4-n-decyloxy-benzylidene)-4'- aminobenzoate] using Z-scan technique. The measurements were carried out using a Q-switched, frequency doubled Nd:YAG laser producing 7 nanosecond laser pulses at 532nm. The Z-scan result shows that the compound exhibits negative non-linearity. The nonlinear refractive index and nonlinear absorption coefficient of this compound were found to be -1.283 � 10-11 esu and 2.232cm/GW, respectively. The real and imaginary parts of the third-order nonlinear optical susceptibility were of the order of 10 -13 esu. The results suggest that these molecules are potential nonlinear optical materials for device applications. Copyright � Taylor & Francis Group, LLC. | en_US |
