← ScienceWhich consequence results when the pulsed laser's divergence exceeds limits?
A)Reduced energy at target plane✓
B)Increased pulse duration broadening
C)Improved spectral linewidth narrowing
D)Enhanced spatial-coherence maintenance
💡 Explanation
Exceeding the divergence limits causes reduced energy density because the beam spreads due to diffraction, therefore, the laser's energy is distributed over a larger area, leading to lower intensity, rather than focused power.
