| Popis: | The spectral output of a TEA CO2 laser utilizing nonconventional CO2/H2 and CO2/N2/H2 gas mixtures was analysed. A simultaneous multiline output in P-branch of the 00°1→10°0 transition was recorded. A domination of the P(18) line is typical for the first, and that of the P(20) line for the second gas mixture. The enhancement of the P(18) line intensity in spectra (different from P(20) line domination-CO2/N2/H2 mixture) is explained primarily by a smaller contribution of the R(23) line gain (0111→1110 CO2 band), to P(20) line (00°1→10°0 band). All measurements were conducted with a nondispersive optical cavity. |
