There's way better handheld cutting tools that cut far better than that slow and awkward thing. A plain old oxy/acetylene torch would have done the same job in 1/4 the time and produced much smoother cuts.

Ever wonder what would happen if you took a Mason jar of nitroglycerine and affixed a hickory handle to it and used it as a framing hammer?
No?
Me neither.

And it wouldn't scorch whatever happens to be sitting 10 feet behind whatever you're cutting. And it wouldn't take a couple MW power source.

You're saying that like it's a bad thing...

And a plasma cutter would be even faster and smoother than that.

The proper tools for metal cutting can be found in the linear shaped charges aisle at Home Depot.

It's not scorching what's behind--note how the overshoot beam is a big circle, not a point.  The laser is obviously focused at only one point.  And that thing probably only draws tens of watts.

That seems unlikely.

Note also how the backstop is reflective metal. And how the worker is wearing not only eye shielding, but a full-body reflective thermal suit. The flying sparks show that there's a lot of forced air blowing past the work zone; a laser alone doesn't blast sparks away in the direction of the beam.

Everybody wants a light-saber-style handheld laser that can cut through steel. Nobody thinks about how reflective steel is, and how much glare is going to be blasting around in everybody's faces. Handheld laser swords make about as much sense as hand-grenade toothpaste.

jfarkinB: hand-grenade toothpaste.

Do you mean hand grenades full of toothpaste, or toothpaste that contains hand grenades?

Probably in the low kW range

I have a 40W laser, and it won't do anything to metal.  Without the lens, it will barely mark paper.
Depth of field is not enormous either, it would be very difficult to use it handheld.

Wait,. why not just buy an existing burning class laser? There's plenty of handheld options, even if most won't melt metal admittedly..

It would look something like this....

There are no circumstances in which I could be given this laser and not end up on Fark the next day.

Depends.  With a large enough laser, I think we can skip past 'needing' and get to the point where immediate medical assistance would be a moot point.

So, the takeaway:  It's a great idea for your enemy to use?

Shut up, you! Lasers!

Don't you kill our buzz with talk of practicalities.
