Which consequence results when thermal lensing increases excessively in a pulsed laser?

💡 Explanation

Excessive thermal lensing introduces a variable focal point because the optical path changes with temperature-induced variations in the refractive index of the gain medium, therefore the laser average power becomes unstable rather than maintaining steady operation; it impacts mode stability.
