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.
