← ScienceWhich risk increases when circularly polarized laser light experiences stress-induced birefringence?
A)Increased laser coherence length occurs
B)Elliptical polarization state emerges✓
C)Constructive interference is enhanced
D)Group velocity dispersion diminishes
💡 Explanation
A material under stress exhibits birefringence and will alter the polarization state. The incident circularly polarized light will become elliptically polarized because the stress causes variations in refractive index, therefore causing the change rather than linear repolarization.
