摘要
本文提出了一种新的光泵浦方案,考虑了波长在500 nm和1315 nm附近的光的两步辐照。500nm的辐射被用来解离大约1%的碘分子。1315nm处的辐射将碘原子激发到2P1/2态。单线态氧分子通过I(2P1/2)+O2(X3Σ)→I(2P3/2)+O2(a1Δ)的能量交换过程产生,而I(2P1/2)+O2(a1Δ)能量池产生b1Σ氧。然后,I(2P3/2)和O2(1Σ)加速I2的解离。超声速喷管内气体动态冷却后,有效介质可达~100 W cm-2,信号增益可达~0.01 cm-1。
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 2P1/2 state. Singlet oxygen molecules are produced via the energy exchange process I(2P1/2)+O2(X3Σ)→ I(2P3/2)+O2(a1Δ), while I(2P1/2)+O2(a1Δ) energy pooling produces b1Σ oxygen. I(2P3/2) 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.
