激光器功率稳定性氯气压力碘文氏管压力 lasers power stabilization chlorine pressure iodine venturitube pressure

摘要

根据简单饱和增益模型建立的氧碘化学激光器功率模型，理论分析了氧碘化学激光器功率稳定性影响因素。结合氧碘化学激光器实际监测参数，研究了氯气压力和碘文氏管压力对氧碘化学激光器功率稳定性的影响。实验结果表明，在1~6 s时间段内，随着出光时间的变长，氯气压力和碘文氏管压力的均方根(RMS)值变小，同时，较小的氯气压力和碘文氏管RMS值，相应的出光功率的RMS值也会较小，这说明提高氯气压力和碘文氏管压力的稳定性可以提高氧碘激光器出光功率的稳定性。

Abstract

The modeling of chemical oxygen iodine laser power using a simplified saturation model is established. The main factors influencing the power of chemical oxygen iodine laser have been studied theoretically. According to the testing parameter of chemical oxygen iodine laser, the power stability caused by chlorine and iodine pressure has been analyzed. It is found that the root mean square (RMS) of chlorine and iodine venturitube pressure becomes small as the laser time increasing between 1 and 6 seconds, at the same time, the more RMS of chlorine, iodine venturitube pressure, the more RMS of chemical oxygen iodine laser power. Chemical oxygen iodine laser power stabilization increases by improving the pressure stabilization of chlorine and iodine venturitube.
