摘　　要：对级联三能级系统超快调制光谱学（ＵＭＳＣＴＳ）的光谱分辨率进行了研究，发现其对能级差的测量决定于光学跃迁的均匀增宽．在符合拍频条件时，能级差可以超出激光线宽，其测量精度可达到与激光线宽同一数量级．Ultrafast modulation spectroscopy is applied to study the spectral resolution in a cascade three level system. Measurement accuracy for the energy level difference is determined by the homogeneous linewidthes of the optical transitions. For the occurrence of beating, the energy level difference could exceed the laser linewidth while the measurement accuracy could reach the same order of magnitude as the laser linewidth.
