← ScienceWhich risk increases when compressive stress misaligns birefringent material?
A)Increased unwanted optical phase retardation✓
B)Reduced amplified spontaneous emission efficiency
C)Decreased temperature dependent refractive index
D)Enhanced stimulated Raman scattering threshold
💡 Explanation
Misalignment changes stress distribution, modifying the refractive index ellipsoid via the photoelastic effect, which induces Optical Phase Retardation. Because phase retardation increases, stress-induced birefringence worsens, rather than altering material properties or laser functions under different circumstances. Therefore, undesired polarization effects arise
