SimuLase™ Demo

Download a free demo-version of SimuLase™ as well as its full manual and a quick-start guide. You can download a description of real life examples of how SimuLase can be used to design, analyze and optimize e.g. edge-emitting devices and VECSELs. You can also download a demo GainDatabase, a corresponding structure file and some experimentally measured photo luminescence data that allow one to reproduce the example of an edge emitting structure discussed in the examples-guide.
