Luminescence of Xe{sub 2}Cl{sup } upon laser excitation of Cl{sub 2} – Xe mixtures in a wide pressure range

The luminescence of Xe{sub 2}Cl{sup *} excimer upon optical excitation of high-pressure Cl{sub 2} – Xe mixtures by XeCl laser pulses (λ = 308 nm) with different energies is investigated. It is shown that small-signal gain of the Xe{sub 2}Cl amplifier may reach ∼1.3 × 10{sup −1} cm{sup −1} in a mixtu...

Zusammenfassung:The luminescence of Xe{sub 2}Cl{sup *} excimer upon optical excitation of high-pressure Cl{sub 2} – Xe mixtures by XeCl laser pulses (λ = 308 nm) with different energies is investigated. It is shown that small-signal gain of the Xe{sub 2}Cl amplifier may reach ∼1.3 × 10{sup −1} cm{sup −1} in a mixture of Cl{sub 2} and Xe with partial pressures of 4 Torr and 9 atm, respectively, and an excitation fluence of 10{sup 26} photons cm{sup −2} s{sup −1}.
