Lasing threshold

In laser science, the lasing threshold is the lowest excitation level at which a laser's output is dominated by stimulated emission rather than by spontaneous emission. Below the threshold, the laser's output power rises slowly with increasing excitation. Above the threshold, the slope of power vs. excitation is orders of magnitude greater. The linewidth…
