Hi, I have recently gained an interest in converting one of my old CNC machines into a laser cutter/engraver. I came across the PLD-40 fiber coupled laser on ebay for a price within my range, and the most power I had seen on a laser this price and size. Being quite new to lasers i did some research and figured out that this laser basically shoots a beam into the fiber optic cable. (correct me if im wrong please). Now if i wanted to use this as a Cutter/engraver, i would need to somehow focus the output of this fiber optic cable, and i am unsure of how to do that and weather or not this is actually a feasible idea.
