...aging, Murnane said. Moreover,whereas traditional lasers
emit visible and near-infrared light (withwavelengths in the 500-1000 nanometer range), those from the U-M device areabout 20nm, with the possibility of being as short as 2nm. The shorter thewavelength, the higher the spatial resolution of the beam....
