Which consequence arises when multimode laser diodes lose coherence?

💡 Explanation

Increased beam divergence arises from reduced coherence; because spatial coherence degrades, wavefronts spread unevenly due to amplified spontaneous emission. Therefore, divergence worsens, rather than improving spectral density, because diverse lasing paths emerge.
