Paper Abstract

A transversely excited atmospheric (TEA) CO2 laser with gas internal coaxial circulation scheme is presented. To ensure stable discharge the free potential plate UV corona preionization technique is employed. The gas flow velocity reaches 15 meters per second, when the motor rotates at 8000 turns per minute. The TEA CO2 laser is able to operate at 33Hz with more than 106 arcing-free discharge. The minimum clear ratio is found smaller than theoretical limit (root)3.
