← ScienceWhich risk increases when a high-intensity laser excites valence electrons to higher unoccupied orbitals in a dielectric mirror's coating?
A)Increased optical transmittance occurs
B)Stimulated Raman scattering decreases
C)Multi-photon absorption probability rises✓
D)Free-carrier generation rate decreases
💡 Explanation
The risk of multi-photon absorption rises because higher intensity light increases the probability of multiple photons exciting an electron simultaneously via non-linear absorption, thereby exciting electrons past the bandgap rather than standard single-photon absorption.
