很明显的是，在低泵浦能量的状态下，参数q的最大值集中在横坐标零的附近，

It is evident that, in a state of low pump energy, the maximum value of parameter q is concentrated near zero abscissa, shown in Figure 4.1. With increasing pump energy, gradually move closer to the peak value of q ± 1, shown in Figure 4.2.

Obviously, in the low pump energy state, the maximum value of parameter q is concentrated near the horizontal coordinate stake, as shown in Figure 4.1. As the pump energy increases, the peak of q gradually moves closer to .1, as shown in Figure 4.2.

Obviously, in the state of low pump energy, the maximum value of parameter q is concentrated near the abscissa zero, as shown in Figure 4.1. With the increase of pump energy, the peak value of Q gradually approaches ± 1, as shown in Figure 4.2.<br>
