Photo-Detachment of H^- in Magnetized Cascaded Arc Hydrogen Plasma

Abstract:

In the blue region of the magnetized hydrogen plasma the population inversion has been observed. Possible reaction responsible for the inversion is molecular ion recombination that gives an overpopulation of states 4, 5 and 6. This inversion can be eliminated by using Nd: YAG laser, λ=1064 nm (1.15 eV) to photo-detach H- (0.75 eV). Approximately 60% of Hα and less than 10% of Hβ have been destroyed.
