I almost feel bad posting this.

The German police really need to do something about this guy selling these devices.

It can only end badly. To build one privately is one thing to demonstrate a concept but to sell them to potentially irresponsible purchasers is another.

One poster claims to know the laser head used and posted

On the same website, you will see a more accurate representation of what the laser head is capable of [150-200-milli-joules, or 50kW at 4nS 1064nm at 15-Joules of electrical input, 4mm beam].

I don't know the equivolent of 50kw of energy over just 4ns in CW terms but I'm imagining its in the several hundred if not thousands of Watts range. Sounds very dangerous anyway and looking from the wood / plastic damage looks very dangerous!

The TUV will be pleased to hear about this.

Did I also mention this guy has no idea whatsoever as to 1. the damage this device can cause both to humans and materials and 2. the protection and precautions required.

Pulse width, Q-switching and peak power are all new concepts for him.

he knows its dangerous. thats all he needs to know about it.
know something is dangerous - treating it like a dangerous artifact comes automaticly.

you made your points. dont make him afraid of laws.
he's done a awesome piece of work and are you trying to mess that up?

NOT TRUE

Everybody knows fireworks are dangerous, nevertheless thousands of accidents happen in the Netherlands each year just by plain recklessness.

Blinding someone for life is a lot easier with a q-switched class IV handheld then with a firecracker.

recklessness occurs if someone doesnt find something dangerous enough...

All depends on the danger "factor" the person feels at the device.

Are there hazards at play here, that are not even being thought about though?

E.g. at the point you've blown the black paint off that tin, how much harmful radiation gets scattered back off the nice shiny metal surface beneath? How much occular hazard exists?

Exactly. And how much of that is accounted for? Are there warnings?

Even something simple, like trying to punch a hole through a steel razor blade. Put in a few hundred kilowatts in and you're bound to get at least a few watts of diffuse reflections (or even speculars) in your face.

But thats ok, because if you don't think about it, there is no 'danger factor' and so you're saved right?

Even with all the obvious danger of strapping a Q-switched SSY-1 to a pistol grip aside, it did quite bother me with his disrespect towards Twhite who basically called him on his outright lie of 1MW when he didn't even really have a concept of pulse width.

Apparently we're 'hating on him' and we're being 'too serious'.

I don't see what's not too serious about strapping an SSY-1 to a pistol and marketing it as a toy.
