Does this mean lidar is now effective at ranges over a few kilometers? Or does it mean lidar measurements are now more precise?

If lidar effective ranges are greater, what would be the current range using the coherent two-photon method?
LIDAR obeys the inverse square law no? It's really much like RADAR isn't it? It's basically to do with intensity yes? The article seems to me very theoretical, but I guess that's QM (read: Greek) for me.

Nvm. I'm surely in over my head.
