摘要
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D2流量为10~20 mmol/s时, 相对燃料D2而言, NF3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。
Abstract
Combustor parameter of all gas-phase iodine laser is studied using the power of HF fundamental laser as a test criterion. The experimental results show that optimal F flow rate can be obtained as the excessive NF3 flow rate of 30%~70% is used for D2 flow rate of 10~20 mmol/s. Addition of attenuant He is a disadvantage for the F atom production. F atoms can be replaced by Cl atoms with enough DCl added. A source of Cl atoms is prepared for the study of all gas-phase iodine laser.
