Perhaps a little exaggeration, agreed. The wavelengths you want are in the UV end of things, which I assumed would be mostly clumsy CO2 tubes. Just the concept of giving a consumer a high power laser they can&#x27;t even see makes me extremely uncomfortable regardless of how plausible the rest of it is. Mistakes with that sort of thing are permanent, you don&#x27;t get any second chances if you blast out your retina.
