← ScienceWhich risk increases when multiple independent lasers operate in close proximity?
A)Speckle formation reduces pattern clarity✓
B)Reduced overall energy output efficiency
C)Increased thermal lensing instabilities occur
D)Spontaneous emission exceeds stimulated emission
💡 Explanation
Speckle formation increases because spatial coherence from independent lasers creates random interference patterns; this blurs fine details. Therefore, speckle obscures holographic or lithographic patterns created from the laser array, rather than altering efficiency or thermal effects.
