Star Wars - does it have a future?

At work.

Okay, how much thrust does this LASER produce?

Actually, some one of a physics bent could probably work that kind of thing out.

Of course, the numbers would have a deal of 'Error' since we don't know specifics such as Alderan's mean density or composition.

Don't forget that 'Solar sails' are a thing. So... if you have a laser beam... you can push such a sail all the same.

Cheers.

And that's on the receiving end, the light beams impact with the sail and impart kinetic energy. There's no thrust at the origin end.
