Diffraction patterns and nonlinear optical properties of Henna oil

Abstract

AbstractThe diffraction ring pattern and Z-scan techniques are used to estimate both the nonlinear refractiveindex, n2, and nonlinear absorption coefficient, β, of Henna oil using low power continuous wave(CW) visible laser beam. The values of n2 and β are obtained of 1.72 x 10-7 cm2/W and 1.21x10-3cm/W respectively.
