A TEA nitrogen UV laser with high repetition rate
Abstract
A TEA nitrogen UV laser with repetition rates of up to 10,000 pulses/sec was developed. The required fast gas exchange in the active volume is attained in a transverse subsonic flow. Transverse flow is made possible by a symmetric flat plate Blumlein discharge configuration, whereby a second gas discharge serves as return load through the flow. An average power of 20KW at 30KV pulse amplitude is obtained. The laser beam quality is improved with an oscillator-amplifier system, but only for low repetition rates.
