← ScienceWhich outcome occurs when intense laser light illuminates silicon doped with electron traps?
A)Two-photon absorption increases significantly✓
B)Free carriers thermalize near band
C)Auger recombination becomes less frequent
D)Photoluminescence intensity decreases linearly
💡 Explanation
Two-photon absorption is amplified because the high photon flux, combined with trapped electrons undergoing virtual transitions, stimulates another photon absorption event via stimulated emission. Therefore, option A increases, rather than single-photon dominance or decreased intensity at high flux.
