The plasma state for Li-like Al recombination X-ray lasers

Based upon rate equations, the decay constant, population of excited states, inversion factor and small signal gain of Li-like Al recombination plasma as well as their relationship with the electron temperature, and density, and escape probability of photons are discussed. The plasma state objective region which must be established for recombination Li-like Al X-ray lasers have been obtained. The Z-scaling law of these physical quantities is discussed
