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, 4, 5, 6 relative changes as shown in FIG. These experimental results show that, with the change of pump energy, laser sideband undergone a transition from a glassy state to a random state, laser sideband symmetry breaking has occurred
