In the experiment, a continuous-wave laser with a wavelength of 405 nm was utilized to determine the sign and value of the nonlinear refractive (NLR) index and the absorption coefficient with closed and opened apertures of the Z-scan setup. The NLR index was found to increase with the ZnO concentration in the glass samples by an order of 10-10 cm2·W-1. The real and imaginary parts of the third-order nonlinear susceptibility were calculated by referring to the NLR index (n2) and absorption coefficient (β) of the samples. The value of the third-order nonlinear susceptibility was presented by nonlinear refractive or absorptive behavior of phosphate glasses for proper utilization in nonlinear optical devices. Based on the measurement, the positive sign of the NLR index shows a self-focusing phenomenon. The figures of merit for each sample were calculated to judge the potential of phosphate glasses for application in optical switching. 2014-05-23T08:31:46Z 2014-05-23T08:31:46Z 2013-11 Article Chinese Physics B, vol. 22(11), 2013, pages 1-5 1674-1056 http://iopscience.iop.org/1674-1056/22/11/117802/ http://dspace.unimap.edu.my:80/dspace/handle/123456789/34695 en Chinese Physical Society and IOP Publishing Ltd |
