Random Laser Simulation

I am trying to to simulate a system for Random Laser. Basically what I need is to have my laser hit specific part of the sample with certain angle and I am interested in reflected portion of laser and also the angle of reflection. Can any1 help me with this. Is it possible to do that in Comsol if so please give me some ideas for the start. I have done couple of modelling on stress measurement of thin films but now I have moved to random lasers and need to get it right!

Hi
I believe you must define better what you mean by "random" laser. You can simulate the electromagnetic EM propagation of the laser light EM field with the RF, but you need quite a small mesh and rather large PC/WS to do it. See the RF/optics examples. If its "just" to identify reflection w.r.t. a bounce off a surface it's perhaps an overkill, but anyhow interesting as it gives insights very different from ray tracing, that is the standard optical ways to study propagation

Good luck
