利用喇曼光谱测量氧碘激光器氧发生器的O_2(a^1Δ)产率

Measurement of O_2(a^1Δ)yield of COIL singlet oxygen generator using Raman spectroscopy

利用自发喇曼成像技术实时监测氧碘激光器O2(a1Δ)发生器流场组分,得到了发生器气流中O2(a1Δ)和O2(X3Σ)以及N2的自发喇曼散射光谱,由此得到了不同条件下的O2(a1Δ)产率,测量误差不超过8%。

A spontaneous Raman scatting system was used to measure the O2(a1Δ) yield of singlet oxygen generator for chemical oxygen iodine laser. Many common experimental problems, such as fluctuations in laser power, dirty windows, and misalignment, can be ratioed out because of monitoring in the same measurement volume. Present the results from the tests that conducted on 0.1mol/s jettype singlet oxygen generator. The error in the yield measurement is less than 8%.
