摘要
本文从理论上系统地研究了由于五阶极化强度间的干涉所导致的级联三能级系统相位共轭超快调制光谱学． 它对激光绝对频率的测量可达到与激光线宽同一量级的精度． 无论泵浦光束为窄带线宽或宽带线宽，它对能级差测量的总体精度仅仅取决于光学跃迁的均匀增宽，而与激光线宽和多普勒增宽无关．
A phase conjugate ultrafast modulation spectroscopy due to the interference between fifth order optical polarization in a cascade three level system is studied theoretically.The measurement accuracy for laser absolute frequency could reach the same order of magnitude as the laser linewidth.When the pump beams have either narrowband or broadband linewidth,it is found that the overall accuracy for the energy level difference measurement is determined by the homogeneous linewidths of the optical transitions,and is independent of laser linewidth and Doppler broadening.
