| 摘 要： | 从理论上研究了由于五阶极化强度间的干涉所导致的Ｖ型三能级系统相闰共轭超快调制光谱学，考虑了抽运光束为窄带线宽或宽带线宽的情形。发现能级分裂的测量精度决定于光学跃迁的均匀增宽，即这种技术在测量能级分裂时可得到消除多普勒增宽的精度。

| Abstract: | The phase-conjugate ultrafast modulation spectroscopy is studied theoretically due to the interference between fifth-order optical polarization in a V-type three-level system, and considered the cases that the pump beams have either narrowband or broadband linewidth. It is found that the accuracy of the energy-level splitting measurement is determined by the homogeneous linewidths of the optical transitions. It means that this technique can achieve Doppler-free precision in the measurement of energy level splitting. |
