Nonlinear Far-Infrared Magnetoabsorption and Optically Detected Magnetoimpurity Effect in n -GaAs

Measurements have been made of CW nonlinear far-infrared magnetoabsorption in pure, partially compensated n-GaAs. A new optical observation of he magnetoimpurity resonance has been demonstrated. Analysis in terms of a three-level model gives effective lifetimes of about 0.5 microns 'off-resonan...

Description
Summary:Measurements have been made of CW nonlinear far-infrared magnetoabsorption in pure, partially compensated n-GaAs. A new optical observation of he magnetoimpurity resonance has been demonstrated. Analysis in terms of a three-level model gives effective lifetimes of about 0.5 microns 'off-resonance' and 30 ns 'on-resonance', implying the possibility of laser action in the former case.
