is it possible to make a laser beam more powerful by adding more lasers?
iv been looking at the laser cutter 'ables and am wondering it its possible to combine say 10 fairly high powered (cheap/er) lasers into a single beam to create a more powerful burn.
id prefer not to go out and buy $2000 worth of laser which ill most likely break. or get arrested for trying to bring through customs.
i was thinking of using a diverging lens to make the spread out rays in a parallel path. in diagram
i understand that mounting the lasers will be a challenge.. but will constructive/deconstructive interference be a problem.. i didnt listen to well in physics.
any ideas would be appreciated
