Ground loops should not be able to generate magnetic fields that induce fatal currents into typical laser diodes. And by ground i'll just include mains neutral since that is only connected to actual ground at one point typically, but only swings up to a few dozen volts if drawing maximum current from sockets.
Static electricity is something entirely different, it is a charge that can build up if you wear insulating footwear or have well insulating ground surface, mostly if you have both (slide around the nylon carpet in wool socks and such).
It is very manageable though. If you have problems with static electricty (mostly in dry climates and such) you should do you work on a somewhat conductive mat. Some people prefer to use a wrist-wrap connected to that mat to keep static from building up, but that's mostly not required: just put your hands on the mat before handing anything and it's fine.
There are some caveats to it though, if you use for example a chair on nylon wheels riding along a laminated floor you could build up some charge by just moving about.
Often you'll notice this static buildup though. If conditions are just right you'll probably notice getting little shocks from many things, such as touching your car or even a shopping trolley, faucet or door handle. If that happens you need to take more serious precautions.
Same goes for when you get a zap from touching other people - it can be fun for sure but is also an indicator to be extra cafeful with electronics that will not appreciate the romance at all.
