Abstract

A novel optical pumping scheme considering a two-step irradiation by light at wavelengths near 500 nm and 1315 nm is proposed in this work. Radiation at 500 nm is used to dissociate about 1% of iodine molecules. The radiation at 1315 nm excites atomic iodine to the ²P_1/2 state. Singlet oxygen molecules are produced via the energy exchange process I(²P_1/2)+O₂(X³Σ)→ I(²P_3/2)+O₂(a¹Δ), while I(²P_1/2)+O₂(a¹Δ) energy pooling produces b¹Σ oxygen. I(²P_3/2) and O₂(¹Σ) then accelerate the dissociation of I₂. After gas dynamic cooling in supersonic nozzle, active medium may reach ~100 W cm^–2 and small signal gain of ~0.01 cm^-1.
