摘要

本文提出了一种测量碘原子在光解激光器中52P1/2→52P3/2跃迁截面的新方法。利用激光辐射在活性介质中的动态自衍射来监测碘原子的逆复合。我们测量了H-C3F7I和CF3I与Xe混合物的截面。这种新方法大大提高了测量截面的精度。结果重现性好,分散度不超过3%。

A more accurate method of measuring the cross section for the 52P1/2→52P3/2 transition of atomic iodine in photodissociation lasers based on dynamic self-diffraction
We have developed a new method for measuring the cross section for the 52P1/2→52P3/2 transition of atomic iodine in photodissociation lasers. The inverse recombination of iodine atoms is monitored via dynamic self-diffraction of the laser radiation in the active medium. We have measured the cross section in mixtures of H-C3F7I and CF3I with Xe. This new method substantially increases the accuracy with which the cross section can be measured. Our results are highly reproducible, with a dispersion of no more than 3%.
