Computationally, Density Functional Theory is employed to investigate the thermodynamic and geometric properties of molecules. The B3LYP hybrid functional and the 6-311G(2d,p) basis set are employed to determine the HOMO, LUMO energy, and Hirshfeld atomic charges. The electronic spectrum was studied using CAM-B3LYP and 6-311G(2d,p) bases sets of the 1,4-DHP-CHO compound. A continuous wave 473nm laser beam with Gaussian intensity profile in the x–y plane propagates along the z-axis traverses dihydropyridine, producing diffraction patterns. We have studied the diffraction patterns temporal evolution, the effect of laser beam wave front and the variation of the power input. The diffraction patterns appeared symmetric with respect to the z-axis then they lose symmetry and appeared asymmetric when the thermal convection current overcome the conduction thermal current. The number of rings in each pattern and the closed aperture Z-scan are used to estimate the nonlinear refractive index, n<sub>2</sub>, of the sample.
