SPASER

The Laser of Nanotechnology

SPASER stands for "surface plasmon amplification by stimulated emission of radiation". It was first described in 2003; and the first actual device was announced in August 2009.

This device was composed of a tiny gold nanoparticle with a core surrounded by dyed silica, created by researchers from Norfolk State, Purdue and Cornell universities.

The spaser is proposed to be a nanoscale source of optical fields, which are being looked into in many prominent laboratories around the world. If it functions as planned, the "laser of nanotechnology" could be applied to a wide range of applications, such as microscopy and nanoscale lithography.
