Which outcome occurs when excessive vibration perturbs laser mirrors?

💡 Explanation

Speckle occurs due to interferences of coherent light scattering; motion introduces path length variations, and thus, speckle shifts because vibration modulates the interference pattern. Therefore speckle shifts rather than facet reflection changes or medium changes due to vibrations.
