← ScienceWhich mechanism amplifies an excimer laser's power output?
A)Stimulated emission of coherent photons✓
B)Spontaneous decay of excited dimers
C)Resonant energy transfer of phonons
D)Non-linear self-focusing of incident light
💡 Explanation
The mechanism responsible is stimulated emission, because incoming photons induce excited excimer molecules to emit more photons having the same wavelength and phase, therefore amplification occurs, rather than relying on spontaneous emission or other non-coherent interactions.
