These shows are done with a 8-16 Watt Lasers, that can easily cut trough arm-thick steel.
Somehow I don't think a 16W laser could cut a hole in arm thick steel.

Still, nice video.

I wonder who came up with that indeed... steel is pretty reflective as it is, but even if it were all absorbed i doubt very much that 10 watts would even cut a milimetre thick sheet... certainly not unless focussed on a tiny spot.

I'm not sure any laser can cut through arm thick (length or width?) steel reliably.

We'll see what the military has to say about that. *

I saw this video a while ago... it made me want one. The photos are nice. I wonder if they needed permission to blast a 16W beam halfway across the city. Onto buildings.

Oh, that might very well be possible, but as these are green DPSS lasers they are probably just plain CW or operated at a large duty cycle.

16W average with a limited repeat rate and nanosecond pulses would surely 'cut' arm (or tree) thick steel, albeit it more ablating than cutting operated like that... a matter of vaporizing a bit each pulse of before heat can conduct away.

I wonder how many people in the city saw those beam shots! *

My RPL could do that! *:P

But I don't have the ballz, or maybe I'm just smart and wouldn't ever do that.
