This patent discloses a nuclear charge Z lasing on a 3-2 Balmer-a transition, a second hydrogenic ion having a nuclear charge Z2 emitting Lyman-a and Lyman-B photons, wherein n2 electrons of he first hydrogenic ion are excited to the n4 and n6 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
