Measurements of Nonlinear Absorption and Refraction Coefficients of Pure and Nd Doped Calcium Lanthanum Borate Glasses
Gajanan B. Harde
Abstract: In the present work, we have calculated optical nonlinear absorption and refraction coefficients of pure and Nd doped calcium lanthanum borate (CLB) glasses prepared by melt quenching method. The measurements were carried out using a single beam z-scan method. Under a linearly polarized continuous wave (cw) He-Ne laser beam at 0.6328?m (red) having 10 mW output power, samples were excited. A closed aperture z-scan method was adopted for nonlinear refractive index (n2) measurement and nonlinear absorption coefficient (?) was measure by using an open aperture z-scan setup. Study shows the values of n2 and ? for pure and Nd doped CLB glasses are significant.
