← ScienceWhich consequence results when a resonant cavity containing a non-linear crystal experiences excessive pulsed laser energy?
A)Optical damage threshold achieved✓
B)Increased group velocity dispersion
C)Improved phase-matching bandwidth
D)Reduced parametric gain coefficient
💡 Explanation
Optical damage occurs as excessive photon energy causes multi-photon absorption within the crystal, initiating avalanche ionization exceeding the material's damage threshold because of amplified energy transfer, therefore, bulk damage arises, rather than enhanced function, under high intensity.
