ABSTRACT:
The disclosed source of coherent radiation is of the type adapted to provide an inversion layer of electrons. The preferred embodiment comprises a grated MOSFET having gallium arsenide or indium antimonide substrate so as to provide a source which is (1) operable at room temperatures, and (2) self-exciting in response to predetermined, substantially constant DC current levels of gate voltage and source-drain voltage.
