Main Question or Discussion Point
Hello, I am pretty new to physics but have a large amount of experience with Calculus and other sciences like chemistry. The theory I have come up with is that if I combine 6-8 5w laser beams together in a convex lens that can be moved forward or backward to change the focal point distance, I could harness their power together to create one 30-40w laser beam. So, my question is, would it work better to use different powered beams together, or one single power with multiple beams. Is there a tool that I could put at the focal point that would make the single powerful beam a "unit" and stay as one beam as opposed to separating into their original beams after exiting the lens, and also, would it in fact combine into a 40w beam or just be one big 5w beam.
