is it possible to make a laser beam more powerful by adding more lasers? Answered
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 grim out.
