利用连续流光腔动力学模型,对氧碘化学激光(COIL)和基于NCl(a)-I传能的全气相碘激光(AGIL)的能量提取进行了分析和公式推导,得到了连续流光腔的光子通量解析表达式以及氧碘化学激光光子通量沿流动方向的分布和输出功率的简化计算公式。AGIL的体系较为复杂,不能得到光子通量沿流动方向分布和输出功率的简化计算公式。从能量提取和体积重量效率角度,对氧碘化学激光和基于NCl(a)-I传能的全气相碘激光进行了对比评价。 Using continuous flow optical cavity dynamics model, the energy extraction of COIL and Gaseous iodine laser (AGIL) based on the NCl (a) -I energy transfer was analyzed and the derivation was derived. The continuous flow cavity Photon flux analytic expression and oxygen iodine chemical laser photon flux along the flow direction of the distribution and output power of a simplified formula. The system of AGIL is more complex and can not get a simplified formula of photon flux distribution along the flow direction and output power. From the perspective of energy extraction and volumetric weight efficiency, the oxygen-iodine chemical laser and the whole-phase iodine laser based on NCl (a) -I energy transfer were compared and evaluated.
