化学法生成碘原子应用于氧碘化学激光器的理论模拟

分析了化学法生成碘原子应用于COIL的优缺点,根据化学法生成碘原子的反应体系和氧碘化学激光器的反应机理建立了一维气体流动预混理论模型,从理论上研究了ClO2与NO反应生成Cl原子的产率随反应器压力的变化,加入HI的位置对生成I原子的影响,化学法生成碘原子代替碘分子注入到COIL中的小信号增益沿气流方向的变化,并与加入碘分子时进行了对比.

Numerical simulation of a chemical oxygen-iodine laser with chemical generation of atomic iodine

One-dimensional pre-mixed model for a COIL, in which the iodine molecular was substituted by iodine atomic, was established. Atomic iodine is generated via a series of chemical reactions of ClO2. NO and HI. The dependence of the vield of the intermediate atomic chlorine on total pressure was studied, as well as the influence of HI injection position on the yield of atomic iodine. The small signal gains both of the COIL with molecular and atomic iodine injection were compared. The system of atomic iodine injection is promising to increase the output power of COIL.
