Diffraction ring patterns, Nonlinear refractive index, Methyl red, Convection currents.


Nonlinear refractive index, n2, of methyl red is estimated at the visible (532nm) laser beam via the generation of diffraction ring patterns. As high value as 5x10-7cm2/W for n2 is obtained. Nonsymmetries in the diffraction ring patterns in the y-direction are noticed as a result of convection currents in the vertical direction.
