Evaluating the prospects of exciting the Xe2Cl active medium by laser radiation for amplifying femtosecond pulses

The possibility of exciting the Xe₂Cl active laser medium produced upon photoassociation Xe + Cl + hν → XeCl(B) caused by absorption of XeCl laser radiation at 308 nm followed by a three-particle recombination to Xe₂Cl(4 ²Γ) is considered. The main pump parameters determining the small-signal gain are estimated, which is of practical interest for amplifying femtosecond laser pulses.
