单重态氧发生器是氧碘化学激光器的核心部件 ,O2 (1Δ)和水汽的粒子数密度 (绝对浓度 )是单重态氧发生器的两个重要参量 ,其中O2 (1Δ)是氧碘化学激光器的能源 ,而水汽对氧碘化学激光器的发光介质—I 有强烈的淬灭作用。如何简单准确地测量这两个参量 ,一直是氧碘化学激光器研究中的一个难题。利用体光源模拟标定法 ,得到了O2 (1Δ)和水汽的绝对浓度 ,并且成功地用一套实验装置对射流式单重态氧发生器的上述两个参量进行了实时测量 ,得到了两个参量的变化曲线 ,同时还提供了O2 (1Δ)的产率以及水汽体积浓度等参量的变化曲线 ,通过大量实验结果 ,给出了各参量的变化规律 ,为射流式单重态氧发生器研究提供了有力的参考依据。
The singlet oxygen generator is the core component of oxygen-iodine chemical laser. The density number (absolute concentration) of O2 (1Δ) and water vapor is two important parameters of singlet oxygen generator. O2 (1Δ) Chemical laser energy, and water vapor on the oxygen-iodine chemical laser light medium-I have a strong quenching effect. How to measure these two parameters simply and accurately has been a difficult problem in the research of oxygen-iodine chemical laser. The absolute concentration of O2 (1Δ) and water vapor were obtained by using the body light source calibration method. The above two parameters of the jet singlet oxygen generator were successfully measured by a set of experimental devices in real time. Two The curves of O2 (1Δ) yield and the variation of vapor volume concentration and other parameters are also provided. Through a large number of experimental results, the variation law of each parameter is given, which is the research of jet singlet oxygen generator Provide a strong reference.
