 In-progress videos of various circle sizes both front and back, being laser cut by Prestige Graphics.  

From the Prestige Graphics, INC website, "Laser cutting technology works by directing an output high-power laser, by computer, at the material to be cut. The material then either melts, burns or vaporizes away leaving an edge with a high-quality surface finish. Advantages over mechanical cutting are: lack of physical contact, precision and a reduced chance of warping. Some materials are also very difficult or impossible to cut by more traditional means."
