A sealed high-repetition-rate TEA-CO/sub 2/ laser
Technical Report
·
OSTI ID:6554650
A compact atmospheric pressure CO/sub 2/ laser utilizing a double-discharge technique was constructed and operated at moderate repetition rates. With the addition of small amounts of hydrogen and carbon monoxide to the He-CO/sub 2/-N/sub 2/ gas mixture, sealed operational lifetimes exceeding 2x10/sup 6/ pulses were obtained. Operating in this mode, the output energy is about 250 mJ/pulse at repetition frequencies of 40 to 50 pulses/s.
