• Transient photoinduced absorption in As2Se3 and Ag(Cu)-doped As2Se3 glasses was measured after the samples were excited with an intense laser pulse with a pulse width of 10 ns, a peak optical intensity of ${\sim}100$ MW/cm2, and a wavelength of 1.064 μm. The decay time of the nonlinear absorption was within 15–21 ms. A photocurrent experiment was also performed under the same illumination conditions, but we observed no photocurrent. Such a slow nonlinearity is presumably attributed not to free-carrier effects, but to photoinduced effects related to wrong bonds in the glasses.
