Abstract

We describe an interferometric technique based on high precision two-dimensional spatial fringe analysis Fourier method. Such a method is used to investigate the characteristic ring diffraction pattern generated by the self-phase-modulation (SPM) effect induced in nematic liquid crystals (NLC) by an infrared laser beam. The experimental set-up employs a Mach-Zehnder interferometer with a c.w. CO₂ laser emitting at 10.6 μm and a pyroelectric optoelectronic sensor array to detect the modulated ring pattern intensity distribution formed in the far field by a nematic E-7 sample. And accurate determination of the nonlinear refractive index can be obtained by analyzing the two-dimensional phase distribution of the ring pattern. (Summary only available)
