Investigating possibilities of attaining large gain-length products on the recombination scheme using lithium-like ions, we have examined two approaches aimed at overcoming the problem of plasma non-uniformity susceptible to destroy gain by a number of processes. In the first approach we studied amplification on the transitions 5f-3d and 4f-3d in Li-like Al{sup 10+} plasma column produced by smoothing optics using lens arrays. Employing this device resulted in the gain holding up significantly longer than when no smoothing optics was used. Second, we have investigated numerically and experimentally the 5g-4f transition in Li-like S{sup 13+}, as the gain should be barely affected by the plasma nonuniformities. Encouraging results were obtained and their various aspects are discussed.
