Abstract

Two photon absorption (TPA) coefficients in HgCdTe have been calculated for CO² laser at 40, 77, 150 and 300 K using Basov formula, both in the parabolic and non-parabolic band structure approximations. Temperature and composition dependent energy gaps have been included in these calculations. Reasonable agreement is obtained with available experimental data.
