Fiber coupled laser diodes: this tutorial provides an overview of the technical properties of fiber-coupled laser diodes. The various laser diode families such as DFB laser diodes or multi-emitter high power laser diodes will be described in this tutorial. Laser diodes are everywhere today.
Figure 3 shows a energy band diagram for a simple edge-emitting laser. In the simplest case it's a p-i-n diode (where i is for intrinsic), an it's an improvement on a regular p-n diode, as an energy well is desirable for trapping the carriers so that they have a chance to radiatively recombine.

4.1 Laser Diode. The LIM requires a continuous wave (CW) laser input whose wavelength is in the visible range. A number of commercially available laser diodes were studied based on the following criteria to identify the most suitable diode for the laser system:
This tutorial will address some of the basics for laser diode handling and operation that should be kept in mind when creating a laser diode system. We shall discuss below: damage mechanisms, specifications, diode packages, mounts and drivers, and some general tips on common laboratory phenomenon that can lead to diode instability or damage.
The simplest way to analyze and understand laser dynamics is using rate equations. In this Chapter, we will setup laser rate equations using the Fabry-Perot optical cavity as a model.
