Nonresonant Nonlinear Absorption in n-Ge, GaAs, and ZnSe in the Long-wave Infrared

Not Accessible

Your library or personal account may give you access

Abstract

We measure nonlinear absorption in semiconductors using nanosecond and picosecond CO2 laser pulses. Absorption strength scales inversely with band gap energy. Effective absorption coefficients in n-Ge are unchanged over intensities from 0.1-2 GW/cm2.
