← ScienceWhich effect results near the focus of pulsed laser?
A)Multi-photon absorption occurs strongly✓
B)Rayleigh scattering becomes dominant
C)Stimulated raman scattering is quenched
D)Linear refraction is not observable
💡 Explanation
Multi-photon absorption occurs primarily because of extremely high intensities near the focal point of the laser. Therefore, it dominates, rather than linear processes, because the probability scales with intensity to the power of the number of photons.
