ABSTRACT
Measures the intensity-dependent intersubband absorption in gallium arsenide/aluminum gallium arsenide quantum wells with far-infrared free-electron laser. Observation of complete bleaching of the absorption at 200 kilowatts per square centimeter; Discussion on the finite pulse width of the laser; Account on the time constant of the two-level system.
