Beyond the gain threshold, some time after the buildup phase, the laser reaches steady state. Neglecting the spontaneous emission, saturated gain and steady state power can be calculated:

The algorithm for location of the cw states in general TW model was developed during the recent study of SL emission''s linewidth in external-cavity diode lasers . In many applica-tions, however,

In the steady state the loss equals the generation: Note that this is the total output power from both ends of the laser. If the two end-faces have equal reflectivities, then half the power will come out each end.
Role of spontaneous emission in the formation of the steady-state
Thus, expressions (26) for the spectral density of ampli-tude, electron concentration and frequency fluctuations allow diode laser noise related to spontaneous emission and steady-state random pump

This paper investigates the steady-state behavior of a semiconductor laser subject to arbitrary levels of external optical feedback by means of an iterative travelling-wave (ITW) model.
Presentation
The laser at threshold is similar to a filled bathtub. Any additional water spills over the side. Likewise any additional injected carriers will “spill out” as stimulated emission and will not increase the carrier density.
