Which consequence results when a short-pulse laser induces avalanche ionization in transparent material?

A)Optical breakdown will permanently damage it
B)Thermal conductivity decreases dramatically then
C)Refractive index remains completely unchanged
D)Stimulated Brillouin scattering reduces energy

💡 Explanation

Permanent damage from optical breakdown occurs because the mechanism amplifies free electrons, increasing absorption and plasma formation. Therefore catastrophic failure happens, rather than index changes because high intensity light causes immediate damage.
