Hussain Ali Badran, Alyaa A. Jari


The nonlinear optical properties of 3-[[(4-methyl -1-piperazinyl) imino]-methyl] –rifamycin VS (rifampin) in Tetrahydrofuran (THF) are studied by using z-scan and diffraction ring technique with continuous wave (CW) laser at a wavelength of 532 nm. The sample showed negative and large nonlinear refractive index values of the order of 10-7 cm2/W and reverse saturable absorption with high values of the nonlinear absorption coefficient of the order of 10-3 cm/W , and the thermooptic coefficients, dn/dT are found to be of the order of 10-6 K-1. The nonlinear refractive index was found to vary with the concentration. The transmitted beam profiles, the distribution of intensity corresponding to the sample positions and D- distribution of rings number of each pattern variation for the rifampin samples have been studied. These results indicate that the sample is a promising candidate for applications in nonlinear optical field.
