<p>A CO2 laser for operation in a repetitive pulsed mode has a slab electrode assembly in which elongated metal electrodes are spaced apart by ceramic insulators attached along aligned edges of the electrodes. An RF potential applied across the electrode causes a discharge in a gas mixture in a gap between the electrodes. At least one aperture extends through each insulator and is aligned with the gap for providing gas movement through the insulator into or out of the gap. Providing the apertures through the insulators increases the maximum pulse repetition frequency of the laser at a given duty cycle compared with that of a similar laser in which the insulators do not have any aperture for providing such gas movement.</p> |
