Fig. 1. Pulse profiles of input waves W3 and W2. A, B, and C are the three calculation points in the following simulation corresponding to t=0, 50, and 100 ps, respectively.

Fig. 2. Intensity and phase evolutions of the three interacting waves. (a) Intensity evolutions of W1 (blue solid curve), W2 (red solid curve), and W3 (black solid curve) within the crystal. The black dashed curve represents the calculated value of sin θ. (b) Phase evolutions of W1 (blue curve), W2 (red curve), and W3 (black curve) within the crystal. All the intensities and phases in this figure are calculated at point A, as shown in Fig. 1.

Fig. 3. Intensity evolutions of W2 at three different temporal points. The black, red, and blue curves correspond to points A, B, and C in Fig. 1, respectively.

Fig. 4. Intensity and phase evolutions of W1 (blue curves), W2 (red curves), and W3 (black curves) under the conditions of αLnl=2 [(a) and (c)] and 8 [(b) and (d)]. All calculations correspond to point A in Fig. 1.

Fig. 5. Intensity evolutions of W2 under the conditions of αLnl= (a) 2 and (b) 8. The black, red, and blue curves correspond to points A, B, and C in Fig. 1, respectively.
