Abstract

Nonlinear refractive index measurements have been made at 1.06 μm using a time‐division interferometer, and n2 measured to be about −3×10−17 m2 W−1 for a TM pump and TE probe. The refractive index change was also seen to contain a positive component at small pump‐probe delay times, corresponding to an intensity‐dependent nonlinear refractive index of n2≊2×10−17 m2 W−1.
