Which issue arises when high-power lasers induce heating?

💡 Explanation

Thermal lensing occurs because increased temperatures creates a refractive index gradient, therefore causing the laser beam to diverge, rather than the laser shifting modes, requiring less heat or lower performance, which leads to gain reduction affecting intensity.
