Abstract EN
We report the observation of multiple diffraction rings patterns in paprika and pepper oils using continuous wave laser beams .The patterns occur at relatively low intensities .
The number of rings together with outermost ring diameter of each pattern increases monotonically with increasing input power .
The total changes in refractive index , ∆n ,and nonlinear refractive index,n2 ,are determined using the number of rings observed in both samples and 473 nm and 532 nm laser beams .
We obtained good values of ∆n = 0.01 and n2 = 10-6 cm2/w .
These large values are attributed to thermal effects
