← ScienceWhich outcome would occur if the adaptive optics system fails in a high-powered fiber laser?
A)Thermal lensing significantly reduces beam quality.✓
B)Stimulated Raman scattering becomes dominant.
C)Mode-locking introduces disruptive temporal instability.
D)The pump diodes experience catastrophic reverse breakdown.
💡 Explanation
Thermal lensing is dramatically amplified by the failure of adaptive optics because the refractive index changes with temperature. Therefore, beam quality decreases rather than other nonlinear effects or electrical failures dominating.
