碘气流穿透深度和碘流量对COIL激光输出功率的影响
Influence of penetration depth of iodine flow on COIL output power

摘要: 通过采用Cl2流量250mmol/s列管射流式氧发生器的COIL出光实验，得到了激光输出功率随碘副气流相对于氧主气流混合穿透深度的变化规律。实验结果表明，穿透深度对激光功率影响较大，存在最佳穿透深度，约为3.16mm,计算的最佳穿透深度与实验得到的最佳穿透深度基本一致。通过逐步改变供碘系统的碘气流流量，测量激光的输出功率，在实验上证实并找到了COIL的最佳碘流量值，约为4.5mmol/s，这一结果比以往文献所登载的最佳碘流量值要确切。Abstract: The influence of penetration depth of iodine flow on COIL output power was experimentally investigated on a COIL with a 250mmol/s (Cl2 flowrate) pipe-array jet-type singlet oxygen generator. The experimental results showed that penetration depth strongly influences COIL output power, and there is an optimal penetration depth, which agrees well with theoretical calculations.
