Gas flow laser generator.

摘要

It includes a discharge tube 1 provided with a central electrode 14 and with two end electrodes 15, the wall of the tube comprising a central opening 3 and additional openings 10, 11, 12 distributed along the tube in order to inject an active gas across an entry chamber 5, the cross-section of the central and additional openings decreasing from the centre to the ends of the tube. The gas injected into the tube leaves it via its two ends across gas exit chambers 7. Application to carbon dioxide laser generators. <IMAGE>
