<p>An internally-modulated gas laser employing a first discharge tube for generating laser wave energy in which modulation is effected by a second discharge tube which includes solely two electrodes, one of which is a cold cathode and the other of which is an anode. Preferably the first and second discharge tubes and the optical resonant cavity mirrors are physically attached to one another to provide a single unitary structure.</p> |
