← ScienceWhich outcome results when a pulsed laser's intensity fluctuates significantly?
A)Spectral broadening of emission occurs✓
B)Increased chromatic aberration manifests
C)Gain saturation becomes spatially uneven
D)Beam divergence reaches diffraction limit
💡 Explanation
Spectral broadening occurs because temporal fluctuations induce Fourier transformation, therefore broadening bandwidth of frequencies emitted rather than resulting from aberrations, uneven saturation or achieving diffraction limitations under standard conditions; dynamic instability induces mode jumps during pulse.
