Kinetics and fusion laser potential for the terbium chloride–aluminum chloride vapor complex

Abstract
Fluorescence responses of the Tb3+ : 5 D 3 and 5 D 4 metastable levels are presented for the terbium chloride–aluminum chloride vapor complex excited by pulsed KrF laser radiation. Assuming unit quantum yield, excited‐state densities as high as 3×1016 cm−3 (10 J/l) are inferred for the experimental conditions and maintained for times ≳10 μs.
