Yuri Paskover, I. Sh. Averbukh, Yehiam Prior

摘要:

单次时间分辨相干反斯托克斯拉曼散射(CARS)是一种快速测量分子光谱的可行方法。该方法基于飞秒脉冲的短空间扩展,并将脉冲之间的时间延迟映射到宽光束之间的交叉区域上。所发射的CARS信号的图像包含关于无场分子动力学的全部时间信息,从中提取光谱信息。该方法被证明对液体样品的CHBr 3和CHCl 3和这些分子的低振动态的拉曼光谱进行测量。

英文摘要:

Single-shot time resolved Coherent Anti-Stokes Raman Scattering (CARS) is presented as a viable method for fast measurements of molecular spectra. The method is based on the short spatial extension of femtosecond pulses and maps time delays between pulses onto the region of intersection between broad beams. The image of the emitted CARS signal contains full temporal information on the field-free molecular dynamics, from which spectral information is extracted. The method is demonstrated on liquid samples of CHBr3 and CHCl3 and the Raman spectrum of the low-lying vibrational states of these molecules is measured.
