Abstract

This work reports the results of investigations of the dependence of the stability of the laser discharge and of the pulse energy on the repetition frequency of a TEA CO2 laser which was varied by changing the condenser charging voltage the condenser capacitance and the composition of the laser gas mixture (CO2:N2:He 1:l:XHe). It is shown that the pulse repetition frequency can be increased by Increasing the helium contents in the gas mixture and by decreasing the energy input into the discharge (or the energy stored in the capacitor). A design of a laser generating 2OmJ pulses at 20Hz without gas flow across the electrodes is described.
