以HF基频激光功率大小作为判断依据,对燃烧驱动全气相碘激光的燃烧室参数进行了考察。实验结果表明,在D_2流量为10～20 mmol/s时,相对燃料D_2而言,NF_3过量30%～70%时可以获得较大的F原子流量,而稀释He的加入不利于F原子的生成;加入足够量的DCl,可以实现F原子全部向Cl原子的转变,为燃烧驱动全气相碘激光器提供了稳定的Cl原子源。 Based on the HF fundamental frequency laser power, the parameters of the combustor driven by full-phase iodine laser were investigated. The experimental results show that, when the flow rate of D_2 is 10 ~ 20 mmol / s, a larger F atom flux can be obtained when the excess amount of NF_3 is 30% ~ 70% relative to fuel D_2. However, the addition of dilute He is not conducive to the formation of F atoms ; Adding a sufficient amount of DCl can achieve full conversion of F atoms to Cl atoms and provide a stable source of Cl atoms for combustion-driven gas iodine lasers.
