双飞秒激光频率梳光谱测量技术研究进展

双光梳光谱分析技术近年来凭借高分辨率、高灵敏度、宽光谱覆盖和快速测量的优势，在分子和原子光谱分析领域得到了快速发展。从双光梳光谱分析的原理出发，以使用泵浦光源数量为分类依据，对近年来国内外基于不同实现方案的多种双光梳光谱分析技术的原理进行了简要介绍，叙述了在不同数量泵浦光源条件下，不同实验小组提出的多种实验方案，介绍了他们进行的光谱实验结果。随着研究的不断深入，减少使用泵浦光源数量是双光梳光谱仪实现设备小型化的发展方向之一，增多光源则是从一维走向多维的重要发展思路，经典的双光源配置在测量精度和二维化方面起到了重要作用。

Research progress of double femtosecond laser frequency comb spectroscopy measurement technology

With the advantages of high resolution,high sensitivity,wide spectral coverage and rapid measurement,the dual-comb spectroscopy technology has developed rapidly in the field of molecular and atomic spectroscopy.According to the principle of dual-comb spectroscopy and taken the number of pump light sources used as the classification criteria,the principles of multiple dual-comb spectroscopy techniques are briefly introduced basen on different implementation schemes at home and abroad in recent years,the various experimental schemes were described proposed by different experimental groups with different numbers of pump light sources,and the results of their spectral experiments were introduced.With the deepening of research,reducing the number of pump light sources used is one of the important directions for the development of dual-comb spectrometers to achieve miniaturization of equipment,and the increase is an important development idea from one-dimensional to multi-dimensional.The classic dual light source configuration has made important progress in accuracy and two-dimensionalization.
