摘要
简述超快调制光谱学在近几年的研究状况,其对能级差的测量精度决定于光学跃迁的均匀增宽。在符合拍频条件时,两独立光源拍频的频差可以超出激光线宽。
Development and information in the research of ultrafast moudlation spectroscopy in recent years are briefly described.The measurement accuracy for the energy level difference is determined by the homogeneous linewidths of the optical transitions.In the condition of the occurrence of beating,the frequency difference of the beat between two independent light sources could exceed the laser linewidth.The measurement accuracy for laser absolute frequency could reach the same order of magnitude as the laser linewidth.
