Abstract

We have investigated the Ne-like yttrium collisionally pumped laser using a detailed time dependent collisional radiative model within a fluid code (EHYBRID), and post-processors to investigate the effects of refraction and saturation. We conclude that, in addition to that on the twoJ = 2 → 1 lines, gain is generated on theJ = 0 → 1 transition and that this line very closely overlaps theJ = 2 → 1 transition at 155 Å. A 50% reduction in the calculated monopole excitation rate which pumps theJ = 0 → 1 line (a notoriously uncertain quantity) is required to obtain satisfactory agreement with experiment — the same modification as was required for the germanium laser.
