Photoabsorption and ionization cross sections in a seeded CO(2) laser mixture.
Photon absorption and photoionization spectra in a CO(2) laser mixture seeded with selected low ionization threshold additives are presented. Such data are used to determine total absorption and ionization cross sections for some gases and vapors of interest. The results identify tripropylamine as an interesting seedent material, as it exhibits a longer wavelength photoionization effect essentially independent of the primary host laser gases.
