Near Infrared Lasing Transitions in Ar, Kr, and Xe Atoms Pumped by a Coaxial e-Beam
Optimizations of gas composition and input energy were performed for gas mixtures containing a buffer gas and either Ar, Kr or Xe as the lasing gas. The total gas pressure was varied between 1 and 14 bar and the input energy from 0.03 to 0.7 J/cm 3. The excitation source was a small coaxial electron beam with a pumping length of 20 cm and a pulse length of 30 ns (FWHM). From an active volume of...
متن کاملSpectral Line Competition in a Coaxial Electron-Beam- Pumped High Pressure Ar/Xe Laser
In order to study the kinetic mechanism of the e-beam pumped Ar/Xe laser, the temporal profiles of individual laser lines during multiline oscillation have been measured as a function of power deposition (1-12MW/cm 3) and gas laser pressure (2-14bar) using a short pulse (30 ns) coaxial electron beam as excitation source. It was found that the optimum output energy at each pressure was obtained ...
متن کاملPhotoionization dynamics of excited Ne , Ar , Kr , 2 and Xe atoms near threshold
A review of experimental and theoretical studies of the threshold 11 photoionization of the heavier rare-gas atoms is presented, with particular emphasis on 12 the autoionization resonances in the spectral region between the lowest two ionization 13 thresholds (mp P3/2 and mp P1/2, with m = 2, 3, 4, and 5 for Ne, Ar, Kr, 14 and Xe, respectively). Observed trends in the positions, widths, and sh...
متن کاملTHE EXTENDED LAW OF CORRESPONDING - STATES AND THE INTERMOLECULAR POTENTIALS FOR Ar-Ar, Ar-Kr AND Kr-Kr
An inversion procedure is used to obtain from the extended principle of corresponding - states the pair interaction potentials for argon, krypton and its mixture over a tetnperature range from absolute zero to the onset of ionization. The experimentally-reduced viscosity collision integrals obtained from the corresponding - states correlation have been inverted directly to give the reduced...
