Dangerous tattoo remover from eBay is a MILLION watt laser
styropyro
Styropyro tests an eBay laser tattoo removal device and finds it is a roughly million-watt pulsed laser, powerful enough to ignite air in the beam. He had bought it hoping to salvage an Nd:YAG laser cavity.
HN mostly cites it as an example of the absurdly powerful lasers sold cheaply online, and a nod to the channel's DIY laser builds.
