← ScienceWhich consequence directly results when minimizing laser beam divergence?
A)Increased interference fringe visibility✓
B)Decreased spontaneous emission rate
C)Enhanced chromatic aberration effects
D)Reduced momentum of resultant photons
💡 Explanation
Increased beam coherence maximizes the **spatial coherence** of the photons traveling parallel paths resulting in clearly defined superposition patterns; therefore interference fringes become sharp, rather than being blurred because spatial incoherence would inhibit fringe formation.
