I think the problem is you'd have to put the laser system on the area you want destroyed. Lightning can really only kill someone or light stuff on fire - and we already have weapons that can achieve this more easily that mounting a laser system in person. So it doesn't look like this is really forming an effective weapon unless you can direct the lightning, ideally stealthily, to a third location. Maybe it could be mounted to a drone that flies over? I'm still having a hard time imagining a scenario where this provides new leverage.

I thought it was the most Sith thing I'd ever heard.

Imagine Darth Maul and Palpatine dancing in the rain .....
