ABSTRACT:
A laser comprises a cell containing xenon at high pressure and has its walls pervious to high-velocity electrons. The cell is of cylindrical shape and constitutes the anode of a field-emission diode. The cathode of the diode is in the shape of an incomplete cylinder surrounding the anode. Electrons emitted from the cathode thus travel radially inwardly and penetrate the anode walls to excite lasing action. The external electrical connection to the anode is of planar configuration and extends radially outwardly from the anode.
