← ScienceWhich consequence results when a pulsed laser system's Q-switch fails?
A)Reduced average output power occurs✓
B)Increased beam divergence is measured
C)Wavelength shifts result unexpectedly
D)Laser transitions cease immediately
💡 Explanation
Failure of the Q-switch prevents effective energy storage, hindering the population inversion and thus lowering gain. Therefore, average laser output power decreases because pulsed operation degrades, rather than altering beam properties or causing complete cessation.
