SPASER

SPASER Spaser (/ˈspeɪzər/) is a phenomenon that was first described by Bergman and Stockman in 2003.[1] The name is an acronym for surface plasmon amplification by stimulated emission of radiation. The first such device was announced in August 2009, a 44-nanometer-diameter nanoparticle with a gold core surrounded by a dyed silica gain medium, created by researchers from Purdue, Norfolk State and Cornell universities.[2] The spaser is a proposed nanoscale source of optical fields that is being investigated in a number of leading laboratories around the world. If realized, spasers could find a wide range of applications, including nanoscale lithography, probing and microscopy. see more...
