Which phenomenon limits focusing a laser through turbulent media?

💡 Explanation

Atmospheric scintillation limits laser focus through turbulent media because refractive index variations cause beam steering; this effect broadens focus rather than simple attenuation by diffraction or heat-induced distortion, therefore scintillation dominates other effects.
