Abstract

A laser comprises a cell containing xenon at high pressure and has its walls previous to high-velocity electrons. The cell is of cylindrical shape and constitutes the anode of a field-emission diode with the cathode of the diode surrounding the anode. Electrons emitted from the cathode thus travel radially inwardly and penetrate the anode walls to excite lasing action.
