Nonlinear optical properties, 1HNMR, 13CNMR spectrums and Surface morphology of (2-Hydroxyphenyl) [2-(2-methoxy benzylidene amino)-5-methyl phenyl] telluride are studied by using self - diffraction induced, optical microscopy and Z-scan approach. The non-linear absorption of compound was obtained from open aperture and Z-scan approach. The optical behavior for azomethine with polymethyl methacrylate (PMMA) film was studied. The observation of diffraction ring patterns due to the irradiation of the azomethine group by 473 nm continuous wave (CW) laser irradiation.
