Phys. Rev. Lett. 115, 194802 (2015) - Multi-MeV Electron Acceleration by Subterawatt Laser Pulses
So they are using a lesser plasma to be a gain medium for a laser, to make a more laser, to make a stronger plasma wakefield, for a particle accelerator. Rather than starting out with a really powerful laser. Implies tabletop accelerator may be easier now.

Coherent Perfect Absorbers
Interesting research on creating the opposite of a laser, a sort of antilaser. A loss medium basically disrupts a laser, which had been amplified in a gain medium. Demo is near IR. Hoping for slightly more broadband sources. Could be used for laser heat absorbers as a thermal laser receiver in remote power beaming applications...

NFMR is interesting, but will this use the Qi protocol for negotiating the power levels? Plus, if you go this far, might as well do wireless USB since that is the same approximate range.
