Which consequence results when thermal gradients distort laser gain medium?

💡 Explanation

Thermal gradients cause spatially varying index changes within the gain medium, leading to thermal lensing, because heat distorts the refractive index; therefore beam quality degrades, rather than phenomena tied to homogeneous gain or nonlinear frequency conversion.
