首次在氯气流量为110mmol/s、采用方列管型射流式O2(1Δ)发生器(SPJSOG)以及列阵式超音速氧碘混合喷管的COIL装置上,以氮气替代氦气作为载气进行出光实验研究.初步实验获得1.8kW的激光输出功率以及18% 的化学效率.

A chemical oxygen-iodine laser (COIL) with a square pipe-array jet-type singlet oxygen generator (SPJSOG), an array of supersonic I 2-O 2 mixing nozzles and nitrogen buffer gases was developed in our laboratory. In our primary experimental stage, an output power of 1.8kW was obtained for a chlorine flowrate of 110mmol/s, corresponding to a chemical efficiency of 18%. The SPJSOG has shown great stabilities during operation in the case of no gas-liquid separator and cold trap. Although not optimized for the nitrogen buffer gas in our primary experimental stage, the COIL device has shown great potential to approach the performance of the COIL with helium buffer gases.
