A novel laser is proposed for the two-dimensional electrons in semiconductor heterostructures in strong magnetic fields. The laser operates under the two-dimensional Landau quantization with population inversion in the Landau levels. The laser frequency, which is directly tunable by the magnitude of the external magnetic field (H), falls on the far infrared for H∼1 T.

    In order to achieve in configuration space a dimensional reduction from dimension two to dimension one, the lowest Landau level (LLL) projection, also called the Peierls substitution, is not sufficient. One has also, once in the LLL, to take the vanishing magnetic field limit.
