← ScienceWhich constraint limits the maximum possible laser pulse intensity?
A)Optical breakdown of the medium✓
B)Quantum efficiency saturation issues
C)Thermal lensing within gain crystal
D)Population inversion reaches equilibrium
💡 Explanation
Optical breakdown limits pulse intensity. This constraint rises because above a threshold, ionization becomes highly effective via avalanche ionization leading to rapid plasma formation destructive to the medium; therefore breakdown is the constraint rather than efficiency or gain.
