The theory of light amplification in far ultraviolet lasers
Abstract
The amplification of short optical wavelength radiation is considered in thin expanding plasma filaments. The amplification of the spontaneous radiation is associated with the transient nature of the active medium and with the defocusing of the radiation. The fairly general conclusions reached apply to any method for creating a population inversion at short (FUV and X-ray) wavelengths. The specific example of the recombination pumping of H-like ions is considered.
