https://www.youtube.com/watch?v=iVrJUbeuG44 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

https://www.youtube.com/watch?v=iR1Ku5dnbH8 Some green laser pointers not only emit a bright green beam but also invisible radiation at a hazardous level! How do we make invisible radiation visible and how do you test your laser for this? Let's find out! I have a spot on my retina of my right eye from one of these cheap green lasers. It was rated at 10mW, but it was actually 330mW (measured at a laser lab a friend had access to) and it emitted most of that in the IR spectrum. It burned my retina through green laser safety goggles faster than I could blink, and was only partially reflected off a glass cup. Heed this man’s warnings, buy only quality lasers and eye protection, and don’t play around with them, I learned my lesson the hard way.﻿

reputable US outlet.
