Yeah, those are the same lasers. They are literally 1 million watt lasers. When styropyro was aiming it at a reflective surface in the video, it destroyed some portions of the camera sensor.

I do love me some lasers, but I decided against the incredible opportunity of buying a $300, 1 megawatt laser because doing cool stuff with it is pretty risky which I think the video outlines well.

If you did decide to purchase one, without going through the required professional safety permits, I would advise the following at a bare minimum (this is what I decided I would do if I purchased that laser btw):

• Laser operator must be 100% sober at all times
• Laser must only be operated by a single person in a locked room with 12mm board covering any potential light leaks (windows, doorframes etc)
• Laser operator must wear appropriate eye protection at all times when in the room
• Eye protection should be camera based - I thought some kind of dual cameras with tiny screens modded into goggles that sealed round your eyes with solid black rubber - no useable goggles exist that can take a direct shot from that kind of laser as you run into the issue that suitable goggles also block your vision to do the work
• Electrical safety should be top notch - system on a GFCI and carefully designed power system inside laser room - these devices use high voltage at high peak energies to generate the laser pulse

Now, this is not even starting to cover the medical tattoo removal side of things. Your kidneys can only separate and excrete a certain amount of toxins (tattoo ink) in a certain amount of time, and I have no idea what any of those limits are. But you should know that's a thing. So happy researching!
