Enhancement of NF( b 1Σ+) by iodine laser pumping

Enhancement of NF( b 1Σ+) by iodine laser pumping

A peak density of electronically excited free radical NF(b1Σ+) of 5.6×10−10 mol/cm3 has been produced in a subsonic flow by means of intracavity pulsed iodine laser pumping of ground-state iodine atoms and subsequent energy transfer of this electronic energy to NF(a1Δ) free radicals. This concentrat...

Zusammenfassung:A peak density of electronically excited free radical NF(b1Σ+) of 5.6×10−10 mol/cm3 has been produced in a subsonic flow by means of intracavity pulsed iodine laser pumping of ground-state iodine atoms and subsequent energy transfer of this electronic energy to NF(a1Δ) free radicals. This concentration represents a 30-fold increase over previously reported steady-state concentrations and supports the promise of the NF(b1Σ+) species as a potential laser candidate.
