← ScienceWhich limitation results when a pulsed laser's repetition rate increases significantly?
A)Reduced pulse energy output occurs
B)Beam polarization drifts substantially
C)Gain saturation becomes very pronounced✓
D)Optical diffraction fringes sharply increase
💡 Explanation
Gain saturation limits power scaling because increased repetition doesn't allow the lasing medium to fully recover between pulses. Therefore, energy in subsequent pulses drops rather than polarization drifting; this is due to incomplete population inversion.
