Just finished building my 40W(!!!) laser shotgun!!! The output of this laser is complete insanity, and is made up of 8 parallel 5W laser beams totaling to 40W. The parallel beams are manipulated with lenses, sort of like how a choke modifies the spread of a shotgun blast. Follow me on Instagram to see some crazy stuff!! :D https://www.instagram.com/styro.drake/ The massive diode array is powered by a huge lithium polymer battery pack (capable up dumping 250A) and the laser array is regulated by a whopping 24 LM317 drivers. Follow me on FaceBook and see my video clips that don't get posted to YouTube!! https://www.facebook.com/diylaserguy For licensing/usage please email [email protected]. Check out http://laserpointerforums.com to learn more about laser pointers, lasers, and laser pointer companies! I have been a member there for 8 years, and have received a bunch of help from the knowledgeable members there! This is definitely the craziest thing I have ever built, but I hope to beat this invention with something even crazier before too long. :D
