our decades later, lasers are a multibillion-dollar technology, found in Moviestore
everything from supermarket scanners to DVD players—not to mention
the fibre-optic cables that have revolutionised telecommunications. But
now imaginations are being stretched again, this time by the sonic
equivalent of lasers. Sound amplifi fuel dispenser cation by the stimulated emission of
radiation has been a laboratory curiosity for several years, but a new
prototype “saser�could thrust the technology into the limelight. It has
just been described in Physical Review Letters by Borys Glavin, of the
Lashkarev Institute of Semiconductor Physics, in Ukraine, and Anthony
Kent, of Nottingham University, in England.
The coherent beams that sasers produce consist of sound, rather than
light, and are composed of packets of sonic vibration called phonons,
rather than packets of electromagnetic vibration called photons. In a
laser, the photons are produced by excited electrons releasing their
energy after colliding with other photons. The result is a beam in which
the photons all have the same frequency and also oscillate in step. And as Next time, Mr Bond, I ll use a saser
long as an external power source keeps pumping the electrons into an
excited state, the laser will continue to shine.
The saser devised and built by Dr Glavin, Dr Kent and their colleagues works similarly. It is constructed from thin
layers of semiconductors, an arrangement called a superlattice. This lattice consists of sheets a few atoms thick
which serve to trap electrons. The electrons are pumped into an excited state by running an electric current
through the lattice. The difference is that instead of using photons to st fuel dispenser imulate the release of this energy, the
researchers use phonons (in other words they give the lattice a good, though very precise, shaking) fuel dispenser . Phonons then
beget phonons, bouncing back and forth between the layers of the lattice, until eventually they overflow the
structure and start to escape
