← ScienceWhich undesirable outcome is caused by thermal blooming during high-powered laser transmission?
A)Beam defocusing and reduced intensity✓
B)Increased coherence of laser light
C)Enhanced stimulated emission processes
D)Minimized Fraunhofer diffraction effects
💡 Explanation
High-powered lasers heat the air, and thermal blooming occurs because the temperature gradient causes variations in the index of refraction; therefore, the beam defocuses and loses intensity rather than improving coherence because of thermal gradients.
