I want to get lasers that burn and cut. That'd be ace.

I wonder how legal they'll be, though. If they burn plastic, they will most definitely blind and probably cause some serious damage to skin and will set clothes on fire...

Hardly news, they are just making them more available. With the bigger ones, if you get them in your eyes, you'll hear a strange popping noise. That'll be your retina exploding. Eyesight through that eye will go red over the next few seconds, and then you'll probably want to retch as you go into shock.

I sure as hell wouldn't want to be near one of them being waved generally around.

The safety bit concerns me, too.

Nice description of the eye popping, I hope you haven't actually witnessed one of those...

In most of the world the most you can have in an accessible beam before safety becomes much of a legal requirement (In a workplace at least) is 5mW for visible light.

Actually in Germany, they have slightly different regulations, and though the classifications are the same, you start to have legal hoops to jump through at about 1mW.

Our laser safety lecture at Uni was given by a nice lady with a patch over one eye. Her description was a lot longer and more detailed.

I'd be expecting Germany having harsher regulations.

Scary.
A bit like our teacher in the woodworking workshop during vocational training, pointing at a row of rather big rust coloured blotches on the floor next to the planing machine: "See those blotches? Those are from the last guy who thought he was so good he didn't have to put the guard down to the width of the board he was working on".
