Okay.
The lasers, pyro etc. are simulated like a furniture object with patched to DMX emissive components of it material. Some examples are present in the Furniture section, see Animated. But you can't play them without Unlimited dongle.
To make your own laser in LC you will need a .avi video of it recordered on the black background with source in the middle. Than just put it on a special 3D-model of laser, make right dimensions of beam and enjoy!
