Which outcome results when thermal lensing occurs in a laser?

💡 Explanation

Thermal lensing creates a refractive index gradient within the gain medium because heat distorts the crystal introducing optical aberrations and reducing beam quality, therefore degrading mode quality rather than improving laser functionality or scattering, due to heat-induced refraction.
