Claim 1
Independent Claim
129 words
IN A GASEOUS LASER OF THE TYPE HAVING AN ELONGATED ENVELOPE WITH TRANSPARENT ENDS, CONTAINING A GAS FOR LASER ACTION AND HAVING A REFLECTING MIRROR SPACED FROM EACH ONE OF SAID ENDS TO PROVIDE A RESONANT CAVITY BETWEEN SAID MIRRORS, MEANS FOR EMITTING ELECTRONS POSITIONED WITHIN SAID ENVELOPE INCLUDING A PAIR OF SPACED GRIDS POSITIONED SUBSTANTIALLY PARALLEL TO ONE ANOTHER AND SUBSTANTIALLY ORTHOGONAL TO THE ELONGATED AXIS OF SAID ELONGATED ENVELOPE, SAID GRIDS HAVING OPENINGS LARGE ENOUGH FOR FREELY PASSING GAS MOLECULES AND ELECTRONS THERETHROUGH, AND MEANS FOR APPLYING A POTENTIAL TO SAID GRIDS FOR ACCELERATING EMITTED ELECTRONS UNTIL THEY HAVE A SUFFICIENT ENERGY TO PROVIDE INELASTIC COLLISIONS WITH MOLECULES OF THE GAS WITHIN SAID ENVELOPE TO RAISE THE ENERGY OF SAID GAS MOLECULES TO THE PROPER LASER LEVEL.
