Feasibility of construction of a photodissociation laser utilizing the 2P1/2 → 2P3/2 fine-structure transition in the fluorine atom

Calculations of the stimulated emission cross section of a fine-structure transition in the fluorine atom and various experimental results obtained previously are used to analyze the feasibility of developing a photodissociation laser emitting due to the λ = 24.75 μm transition. An estimate is given of the threshold gain and several conditions required to achieve lasing are determined.
