• Large nonresonant optical Kerr coefficient without apparent nonlinear absorption was obtained from ZnSe-doped glass thin films grown by pulsed laser deposition. A third nonlinear refractive index of $+0.87$ to 1.56 cm2/GW and fifth order of $+17.2$ cm4/GW2 were measured for a light beam having femtosecond pulsewidth with photon energy below one half bandgap using the Z-scan method. Besides the enhancement of the nonlinear refractive index results from the two-photon near resonance and quantum confinement effect, the intensity-induced saturation of nonlinear refractive index is explained by the quadratic optical Stark shift.
