Abstract

A corona preionization system for a high repetition gas laser is described. The system has been applied to a 200Hz repetition rate TEA CO2 laser with a 1.5x1.5x40cm3 discharge volume. Because the self inductance of the laser head can be kept at a very low value, short excitation pulses and fast rising discharge voltages are possible. Since the preionizer is incorporated in the main circuit and consumes only a small fraction of the total excitation energy, high overall efficiencies can be obtained.
