Abstract
The nonlinear refractive indices of Yb3+: KY(WO4)2 and Yb3+:YVO4 laser crystals are characterized using a Z-scan technique at a wavelength of 1.08 μm for different polarizations. The results reveal that the nonlinear refractive index of Yb3+:YVO4 is superior to that of Yb3+:KY(WO4)2 and is found to be 1.9×10-15 cm2/W and 1.5×10-15 cm2/W for E⊥c and E∥c polarizations, respectively.
