Abstract : This patent discloses a nuclear charge Z lasing on a 3-2 Balmer-a transition, a second hydrogenic ion having a nuclear charge Z/2 emitting Lyman-a and Lyman-B photons, wherein n=2 electrons of he first hydrogenic ion are excited to the n=4 and n=6 level by resonance absorption of Lyman-a and Lyman-B photons from the second hydrogenic ion. The invention results in an increase in population inversion and gain to saturation, an improvement in overall efficiency and an increase in plasma size. (jhd)
