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 nonparabolic band structure approximations. Temperature and composition dependent energy gaps have been included in these calculations. Reasonable agreement is obtamed with available experimental data. 1.
