I discussed this on IRC yesterday and since this was already talked about with one of my patches I thought to make a topic about it here.
The laser is currently the only non-dropable weapon in the game, which I mostly agree with given the fact a player should not be allowed to have no weapon in most gametypes and picking up a laser offers no advantage as it uses no ammo and is given at spawn time (unless you are in a gametype where the laser is not given to you upon spawning so picking one up can offer the advantage of obtaining it).
However if you use a hackish way to drop the laser it doesn't have a drop model and looks like a small rainbow prism on the ground. So far everyone agrees the laser should have a drop model though I remain to the opinion it should not be dropable in any gametype except Race (as discussed on IRC again, in Race you can start with no weapon including the laser). The Pinata mutator which is currently on hold because of this will probably be an exception as that causes all weapons to be dropped upon a player's death, though picking a laser up would still offer no advantage.
I'm curious what everyone thinks and if anyone is able to fix the laser having no drop model. I don't believe a new model for the laser needs to be made since the drop model should normally be the same model of the gun that you hold attached to your character (3rd person gun model), and the laser not having a drop model is likely just something not specified in the code. I'm also wondering how picking up a hackishly dropped laser in gametypes like DM should act... in my opinion the only thing it should do is be picked up like any weapon when someone walks over it though that wouldn't change anything or offer any advantage (unless the laser could later on become dual-wieldable or upgradable whenever you pick a new one up, in which case it could be dropped only if you were holding it upon death in all gametypes?)
