摘要: 对氧碘化学激光器的单重态氧发生器（SOG）进行了改进，采用横向射流方式，并对该横向射流式单重态氧发生器的性能进行了检测。实验中过氧化氢碱溶液温度控制在－16℃左右,氯气流量为530mmol/s，He与氯气的流量比为3;采用PS法测量单重态氧分子的产率,吸收法测量氯气的利用率和相对水含量。得出如下结论:在不使用冷阱和分离器的情况下，最高单重态氧分子产率达到58%, 氯气利用率在80%以上,相对水含量小于等于0.5;气体达到最大流量时,发生器仍然能稳定地工作。

Abstract: A transverse jet singlet oxygen generator (TJSOG) with BHP liquid driven by a pump circulation was demonstrated. This TJSOG represents the trend for its engineering scalability. In the initial experimental stage, a singlet oxygen yield of 58% was obtained for a chlorine flowrate of 530mmol/s, corresponding to a chlorine utilization of above 80% and a relative water vapor concentration no more than 0.5. The O2 (1Δ) and the water vapor content in the gas were determined from the emission of the 1 270nm and 762nm wavelength, respectively, according to the PistonSource method. Chlorine untilization was measured by detecting the absorption of 340nm light by residual chlorine. The TJSOG can work steadily when the total gas flow rate reaches the maximum．-
