A new model for complex dynamic laser modeling

We present a new distributed time domain model (DTDM) for use in complex laser modeling. Like several other models, we use Maxwell´s wave equations, but with a time dependent polarization in the form of classical electron oscillators (CEO). It is based on the neoclassical rate equations of A. E. Siegman. The unique feature of our model is the use of a virtual electric field used to simulate random spontaneous emission. This approach has not been used before. The model includes effects such as gain suppression, optically induced gratings, and excess noise. We discuss our results and compare and contrast them with other published work.
