光散射测量使我们能够确定向声致发光的转变的特征是捕获的脉动气泡的动力学出现分叉。这些实验还表明，在声致发光(SL)状态下，气泡半径的变化仅为20%，与发射光强度的200倍有关。SL的这种敏感性表明，它起源于激波内爆所产生的那种奇异行为。讨论了该模型对聚变能量标度的理论外推。
Light-scattering measurements have enabled us to determine that the transition to sonoluminescence is characterized by a bifurcation in the dynamics of a trapped pulsating bubble. These experiments also reveal that in the sonoluminescence (SL) state, changes in bubble radius of only 20% are associated with factors of 200 in the intensity of emitted light. This sensitivity of SL suggests that it originates from the kind of singular behavior that arises from the implosion of a shock wave. Theoretical extrapolations of this model to energy scales for fusion are discussed.
