← ScienceWhich outcome occurs when phase matching fails centrally within frequency comb generation?
A)Broadened spectral output bandwidth
B)Reduced power in the carrier frequency✓
C)Increased stimulated Raman scattering
D)Suppressed high harmonic generation
💡 Explanation
Decreased power in the carrier frequency occurs because the phase mismatch disrupts constructive interference during spectral broadening via four-wave mixing; therefore, energy shifts to other frequencies rather than remaining concentrated, rather than suppressing other processes like Raman scattering.
