How much BS can this guy fit in one video

[piemadd]

Though the machine does seem homemade and complex, I do think that this 200w "laser" is a bunch of BS. If somebody that knows a little bit more about lasers and electronics could tell me if this is right or wrong?

 

Thanks!

Uuuummmmmm..... what video?

Here, seems he took 4 50W blue lasers (no idea where he got those, since even a 1W laser can burn stuff IIRC), so a Toal of 200W. Plus, he has an epic focusing system: http://interestingengineering.com/200-mw-handheld-laser-gun-powerful-ever/

The thing with laser is that it concentrates all that power to a very small area with minimal loss, so I'm not surprised that he can do that with 200W.

You can buy them sure but if you use anything above 1mw in public then that's illegal.You can buy a 500 w laser if you wanted to

It will be 200W power input to the lasers. The actual wattage of the light output will be significantly lower. Those kind of laser tubes need pretty hefty cooling.

I started a fire to a piece of wood (actually a waste material from a destroyed fence) with a 10W laser torch within seconds and wood burns at 250C, so all I know is that 200W laser is scary.

I mean a 10W laser will be more efficient than a 200w one, (law of diminishing returns).

 

Lasers like that are only really useful for cutting stuff, as most of the light they produce is actually in the IR spectrum.
