High-resolution Reflection Spectroscopy of Cs D2 Line Studied by High-order-harmonic Detection
摘要
Abstract
In this paper, by numerical analysis the relationship of the modulation broaden index with modulation index using high-order-harmonic detection is investigated. Using the voltage modulation the 2f,4f and 6f harmonic signals about the reflection spectroscopy of 6S1/2(F=4)→6P3/2 transition of the cesium D2 line are also be measured. The experimental results are in good agreement with the theoretical predictions. It is found that narrower line-width can be achieved by higher-harmonic detection than the line-width detected by direct absorption when the modulation index is smaller than 1. 81, 2. 98 and 4. 14 for 2f, 4f, and 6f signals, respectively.
