Abstract
The glasses of system (x)Nd2O3-(1-x)La2O3-8CaO-3B2O3 with x=0 (LaCOB) and 0.03 (Nd:LaCOB) have been synthesized by melt quench technique. 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 µm (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 (β) was measure by using an open aperture z-scan setup. Study shows the values of n2, β and susceptibility (χ(3)) for LaCOB and 3% Nd doped LaCOB glasses are significant.
