Presets

A laser fires only when the optical gain from the pumped medium exceeds the losses of the mirror cavity. Below that threshold it merely glows like a lamp; above it, stimulated emission takes over and output rises steeply and linearly with pump power. This sharp threshold is the defining signature of laser action.

Governing equation

Reading this result: Well above threshold, output climbs almost linearly with pump; the slope (~0.8 here) is the slope efficiency, and lowering cavity loss shifts the whole knee left.
