They're pulsed lasers, iirc. The first version, using the
flash lamps, has to be. Flash lamps don't give a continuous
pumping effect. Reading from what both HELSTF and LLNL has
said, the LED pumped version is a follow-on. The laser guys
are just as excited about the pulsed effects as we are. Rapid
thermal cook-off takes a lot longer (theoretically) and doesn't
work in every situation.

That is just too cool. I'm looking forward to seeing how it turns out.
