Abstract

A more detailed discussion on the recent measurements of the 206.38 - angstrom Ne-like Se x-ray laser linewidths and of the 182.45-angstrom Se laser linewidths. The present line-transfer and line-broadening calculations which indicate that the line profiles of both lasers can be approximated relatively well by Voigt profiles with Gaussian and Lorentzian components due to Doppler broadening and lifetime broadening, respectively. It was also found that the laser line transfer behavior can be treated homogeneously because of non-negligible homogeneous lifetime broadening contributions as well collisional redistribution rates sufficiently large to homogenize the inhomogeneous Doppler contribution. In addition, the implications of these consequences with respect to the proposition that Dicke narrowing could be relevant for these laser transitions and with regard to more current computations indicating that this may not be the case. It was concluded that the experimental data confirm these calculations.
