| Abstract: | Intrinsic semiconductor samples in crossed electric and magnetic fields emit under certain conditions recombination radiation (EMP effect). Conditions are formulated under which this effect can be utilized for a laser. Semiconductors with high mobilities, high intrinsic concentration, high volume lifetime, and small effective masses are required. An EMP laser made of InSb appears to be feasible. |
