Abstract

The measurement of the nonresonant third-order nonlinearity of three chalcogenide glasses is reported. Using the Z-scan technique, both the refractive and the absorptive parts of the nonlinearity are resolved, including their sign. It is shown that Ag-doping of As₂S₃ produces a change of sign and a dramatic enhancement of the nonlinear refractive index. © 1994.
