New nanotube coating enables novel laser power meter

		IMAGE: Carbon nanotubes enable the copper instrument to withstand the intensity of military lasers while precisely measuring their power. Laser light is distributed evenly inside the water-cooled cavity by a mirror... Click here for more information.

The U.S. military can now calibrate high-power laser systems, such as those intended to defuse unexploded mines, more quickly and easily thanks to a novel nanotube-coated power measurement device developed at the National Institute of Standards and Technology (NIST).
