入射激光脉冲强度对超拉曼辐射观测影响研究

The Effects of Laster Intensity on the Observations of Hyper Raman Lines

分析了激光脉冲强度对超拉曼谱的影响.当激光场较弱时较容易产生高频超拉曼谱线且谱线强度和高次谐波谱线强度相当,而此时的高次谐波发射的效率较低.这是由于产生两种谱线不同的物理机制导致的.

The influence of Laser pulse intensity to Ultra-Raman spectraWas analyzed. It is prone to generate high frequency uhra-Raman spectra and line intensities when the laser field is weak, which is equal tothe high- order harmonic line intensities. The efficiency of high-order harmonic emission is low. This is due to produce two kinds of line of different physical mechanism.
