Quenching of NF singlet states in a hybrid chemical-laser system

Quenching of NF (a1Δ) and NF (b1Σ) was studied in a subscale upconversion gain medium that was based on energy transfer from NF (b1Σ) to IF. Quenching of NF (b1Σ) by IF was found to occur at gas-kinetic rates that were large compared to the energy-transfer rate, indicating low efficiency for the las...

Zusammenfassung:	Quenching of NF (a1Δ) and NF (b1Σ) was studied in a subscale upconversion gain medium that was based on energy transfer from NF (b1Σ) to IF. Quenching of NF (b1Σ) by IF was found to occur at gas-kinetic rates that were large compared to the energy-transfer rate, indicating low efficiency for the laser. Significant quenching of NF (a1Δ) by IF was also found to occur at a slower rate than was evident for the NF (b1Σ) state.
