X ray laser with enhanced x ray gain through photodepopulation
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.
