Abstract

Abstract Absolute two-photon absorption coefficients have been measured in ZnSe and CdTe single crystals by means of the two-channel normalization technique. Comparison between TPA experimental and theoretical values shows that the TPA, for 2 h ̵ ω ⪢ E g , is oddly influenced both by non-parabolicity and degeneracy of the energy bands.
