Abstract

We measure the nonlinear refractive coefficient n₂ in BaF₂, LiF, MgF₂, Al₂O₃ and diamond using the Z-scan technique at (lambda) equals 1.06, 0.532, and 0.355 micrometers . Two-photon absorption in diamond at 0.355 micrometers is also measured. The results are in good agreement with a two-parabolic band theory developed for semiconductors.
