I was trying to work out a joke about buying better lasers off of alibaba but it seems that despite being 30 years old they're still orders of magnitude beyond off the shelf options.
partially. The very efficient lasers from alibaba don't have short pulse/high power, so they can potentially be used only as the part of the system - the pumping lasers. The final nanosecond-laser is still a one-off build which though seems to be pretty doable even by a small company if they set their mind to it.
Btw, NIF achieved those recent results by adding strong magnetic field around the target (penny-shrinkers knew that tech for 20+ years :). There are other things like this around that can potentially be similarly useful. Only if somebody had money and interest ...
I’ve seen some pretty wacky structures that involve mechanically forcing permanent magnets together at different orientations to create assymetric magnetic fields that are strongest where they need to be or weak where they would cause problems. Like eddy currents in electric motor housing, or insufficient hold for chef’s knives.
I know motor windings have gotten pretty funky of late to do a little bit of this, but do they do multi tesla magnetic fields that use several different windings to create the same sorts of bias in field strength? The ITER windings seem to be an extremely mild form of this.
