← ScienceWhich consequence results when internal laser diffraction is excessive?
A)Reduced beam collimation occurs✓
B)Increased photon entanglement appears
C)Lower excitation threshold develops
D)Gain medium saturation increases
💡 Explanation
Reduced beam collimation results because excess diffraction spreads the laser's photons at varying angles. Therefore, collimation degrades, rather than photon entanglement increasing, because angular spread interferes with maintaining phase coherence.
