Which consequence results when constructive interference affects laser output?

A)Increased amplitude of coherent light
B)Reduced beam divergence over distance
C)Suppression of unwanted laser modes
D)Wavelength shift towards the infrared

💡 Explanation

Increased laser output occurs when light waves combine in phase. Constructive interference causes an increased amplitude of coherent light because the waves add together; therefore, the laser power is higher rather than being limited by disruptive interference.
