Abstract:
The use of an optimal CO2 – N2 – H2 gas mixture with a high concentration of hydrogen (30% – 40%) was shown to allow the formation of high-power TEA CO2-laser pulses with a base duration of ~ 200 ns whose energy and peak power significantly exceed the parameters of pulses obtained in binary CO2 – H2 mixtures. Considering all the parameters, the helium-free 56% CO2 – 14% N2 – 30% H2 gas mixture at a pressure of 0.7 atm is optimal for the generation of short high-power pulses in the TEA CO2 laser. A small addition of nitrogen ([CO2]/[N2] ~ 10 – 12) to the binary CO2 – H2 mixture not only substantially increases the pulse energy and peak power (by a factor of 3 – 3.5) but also shortens their duration at half-maximum with retention of the total (base) duration.
