Which effect reduces laser fusion efficiency via filamentation?

💡 Explanation

Spatial coherence degradation increases filamentation because intensity variations cause localized refractive index changes disrupting the beam profile during propagation, therefore reducing energy delivery to the target rather than other plasma instabilities, given fixed fluence.
