Which consequence results when insufficient cooling causes misalignment in a high-power laser?

💡 Explanation

Insufficient cooling causes thermal expansion resulting in changes to cavity length, and therefore mode characteristics via thermal lensing; because mode stability depends on cavity length, it destabilizes rather than photon production decrease or other non resonant-scattering.
