Interesting, but probably not cheap:

> This is achieved by having more than 0.5 megawatts peak power

and

> The input peak power up to 1.60 MW (350-nJ pulse energy)

I wonder how much it affects/fries the tissue. HHG also has issues with attenuation.

The paper abstract also says previous state of the art was 300um not 200um like in the press release.




The question is, how long is that power needed.

Edit: "Ultrashort pulses" so likely not much. Because indeed, you cannot burn the human. So the energy consumption likely won't be a problem. Except that it might make the machine expensive to build.


In fact, GP quotes "350 nJ" which is a tiny fraction of a watt-second.


Bulk ordered, that is probably a ~$50k laser. Not nothing, but on the scale of medical device costs, not terrible.
