Which consequence results when excessive laser power exceeds the gain medium's capacity?

💡 Explanation

Thermal lensing occurs because uneven heating induces refractive index variations across the gain medium. This diverges the beam, therefore degrading beam parameter rather than stabilizing its output because it distorts the optics rather than correcting it.
