The radiation source is a p‐Ge cyclotron laser (pulse width about 1 µs, repetition rate 1 Hz) which is tunable in the wavelength range 120 µm < λ < 180 µm by an external magnetic field. It is shown that the photoconductivity is caused by the heating of two‐dimensional electron gas (2DEG). A rough estimation yields relaxation time around 0.46 µs. Because of the low effective mass, this material system is especially interesting for detector applications.
