摘要: 为保证氧碘化学激光器谐振腔的腔镜失调测量结果的可靠性和准确性，建立了使用自准直仪间接测量腔镜失调的方法。测量结果表明，热辐射是引起腔镜失调并造成光束漂移的主要原因，通过采取措施，可以使腔镜失调明显减小。同时证明了该测量方法是可靠的、合理的。Abstract: To insure reliable and accurate measurement results of mirror angular displacement for COIL resonator, indirect measurement was found using electronic autocollimator. Measurement results show that thermal radiation is main reason of mirror angular displacement and results in the beam spot drift for COIL. Adopting measures, the mirror angular displacement and the beam spot drift are obviously reduced. Experiments verify that the measurement method is reasonable and reliable.
