Which adverse effect occurs when a high-powered laser rapidly heats a transparent material?

💡 Explanation

Thermal lensing causes beam divergence because temperature gradients create refractive index variations within the material acting like a lens; therefore, input beam divergence occurs, rather than gain saturation or quantum entanglement effects at these intensities.
