High-Powered Laser DVD Laser

Make a DVD Burner into a High-Powered Laser

The laser pictured above has a peak output measured at 225 mW (average output 200 mW). It's a visible red at about 650nm. It can light matches, pop balloons, cut electrical tape, and so forth. It can do pretty much anything a Pulsar 150 from Wicked Lasers can do, because it's basically the same thing. The only differences? This laser was home-made, and cost about 1/3 the price.
