本文研究在雙態系統的圓偏振脈衝雷射，由氫原子的第一激發態到第二激發態的佔有率變化。變動強度達到|b(pulsed peak)|^2≈1，觀察佔有率變化。佔有率變化在|b(end)|^2≈0，其|b(pulsed peak)|^2≈1或0，因此，紀錄隨強度增強，|b(end)|^2變化，來預測|b(pulsed peak)|^2≈1所在強度位置。在近共振條件下，Δω=±0.02(au)有2個明顯的峰值，峰值與pulsed peak位置差異越大，|b(t)|^2較小。

The circular polarization of the pulse laser induces the hydrogen atoms from n=2 to n=3. With changing the intensity to reach |b(pulsed peak)|^2≈1 , the probability of population is presented. When |b(pulsed peak)|^2 is 1 or 0, there is the relation that |b(end)|^2≈0 at the same time. Therefore, |b(end)|^2 at increasing intensity helps find the intensity at |b(pulsed peak)|^2≈1. At near resonance, detuning Δω=±0.02(au) has two obvious peak. When the peak is far from the pulsed peak respectively, the |b(t)|^2 is small.
