Which limitation arises when high power laser coherence is increased through non-linear crystals?

💡 Explanation

Increased coherence leads to spatial modes having increased sensitivity to optical path length variations; this thermo optic effect causes phase distortion because gradients dramatically alter the crystal properties; therefore, precise control becomes harder rather than spectral narrowing or lower threshold effects.
