Which risk increases when coupling multiple lasers for increased power?

💡 Explanation

Speckle contrast increases because spatial coherence creates interference patterns that intensify bright spots, therefore speckle impairs focused resolution rather than causing reflective amplification, because the issue traces to coherent beam superposition.
