Abstract
It is found that the Avalanche Breakdown far-infrared photodetector responds linearly with incident power, is ∝ Ps, when subjected to a specially coherent signal, for example to the beam of a free electron laser, but responds according to a law, is ∝ Pβs, with 0.5 ⩽ β ⩽ 1.0, when irradiated with incoherent radiation, as from a multimode far-infrared laser. Here the detector signal current is is and the incident signal intensity is Ps.
