The Semiconductor-Laser Rate Equations (SRE) are described by the following:

The semiconductor laser rate equations use two variables to model the behavior of the laser
system: *e* is a complex number, modeling the electromagnetic field of the
laser, while *n* measures the density of the carriers in the semiconductor
material.
*n* will always be non-negative.

The parameters used in these equations are summarized below:

- Decomposition of Complex Field
- Overview of the Equations
- Behavior of Trajectories
- Stability Analysis of the Model
- Normal Form
