A TEA CO2laser with output pulse length adjustable from 50 ns to over 50 µs

By adjusting the proportions of CO
2
and N
2
in a TEA laser gas mixture and by also adjusting the coupling losses of the optical resonator, it is shown that the same laser system can produce laser outputs of relatively uniform energy but with pulse lengths adjustable from
0.05 to 50 \mu
