与钠3S/SUB 1/2/.-->；近共振的强激光和探测激光。3P/SUB 1/2/和3P/SUB 1/2/..-->；4D/SUB 3/2/跃迁分别产生三光子电离电流，用于研究3P/SUB 1/2/中间态的展宽和拉比分裂作为探测-激光调谐的函数。我们发现了一个狭窄的强激光失谐区，在这里，Rabi分裂的3P/SUB 1/2/双重态的峰高比与单色激光场的预测值相反。这归因于有限(约.GHz)激光线宽。
An intense laser and a probe laser in near resonance with the sodium 3S/sub 1/2/ ..-->.. 3P/sub 1/2/ and 3P/sub 1/2/ ..-->.. 4D/sub 3/2/ transitions, respectively, produce a three-photon ionization current used to study the broadening and Rabi splitting of the 3P/sub 1/2/ intermediate state as a function of probe-laser tuning. We find a narrow, intense-laser detuning region where the peak heights ratio of the Rabi-split 3P/sub 1/2/ doublet is reversed from that predicted for a monochromatic laser field. This is attributed to the finite (approx. GHz) laser linewidth.
