What happens when excessive power causes laser crystal thermal expansion?

💡 Explanation

Excessive power causes thermal lensing due to uneven crystal heating. This phenomenon manifests as a lens, resulting in refraction and increased beam divergence; therefore, divergence increases heavily, rather than efficient mode-locking.
