摘要

利用波长可调制的1315 nm二极管激光增益测试系统,对基于HN3反应的D2-NF3-DCl燃烧驱动全气相碘激光进行了小信号增益测试,获得了3×10-5 cm-1的小信号增益,并获得了沿流动方向的小信号增益分布情况。正增益的获得,标志着D2-NF3-DCl燃烧驱动全气相碘激光取得了实质性的进展,但就目前的增益水平来讲,进行出光演示尚有一定的困难,需要针对小信号增益进行全面的参数优化,以获得尽可能大的增益信号,而HN3的大流量供给和超音速混合流场的优化是全气相碘激光获得较大增益的关键因素。

Abstract

The small signal gain measurement of the all gas-phase iodine laser driven by D2-NF3-DCI combustion is taken using a wavelength tunable 1315 nm diode laser gain measurement system. A small signal gain of 3×10-5 cm-1 and the profile of small signal gain along the flow direction are obtained. The positive gain indicates that a material progress has been made in the D2-NF3-DCl combustion-driven all gas-phase iodine laser,but it is still difficult to demonstrate lasing as to the magnitude of the small signal gain,a detailed parameter optimization must be done in order to improve markedly the small signal gain,and the plentiful supply of HN3 and the optimization of the supersonic mixing flow field are key factors to obtain a high small signal gain for the D2-NF3-DCl combustion-driven all gas-phase iodine laser.
