Which risk increases markedly when optically pumping a titanium-sapphire laser crystal?

💡 Explanation

Optical pumping deposits significant heat raising the crystal's temperature. Thermal lensing causes refractive index variations because heat redistributes nonuniformly; therefore, beam quality decreases rather than improving, unless counteracted, rather than the others.
