← ScienceWhich consequence results when laser coherence decreases inside of a microchip interferometer?
A)Reduced fringe visibility appears✓
B)Increased amplifier saturation occurs
C)Enhanced wavelength stability results
D)Improved signal-noise ratio obtains
💡 Explanation
Decreased coherence leads to lower interference contrast because mutual interference relies on consistent phase relationships. Therefore, fringe visibility reduces, because intensity variations depend on wave superposition, rather than enhanced amplifier saturation.
