Florian Aigner, Vienna University of Technology They shed light on atomic and molecular processes: ultrashort laser pulses are required to study extremely fast quantum phenomena. For years, scientists have been trying to tune the shape of light waves so as to, for instance, steer an electron on exactly the right path. At the TU Vienna, an extraordinarily powerful new method to influence the shape of the laser light wave has been developed in cooperation with the Imperial College in London...

In an advance that sounds almost Zen, researchers at the National Institute of Standards and Technology (NIST) and JILA, a joint institute of NIST and the University of Colorado at Boulder, have demonstrated a new type of pulsed laser that excels at not producing light. The new device generates sustained streams of "dark pulses""”repeated dips in light intensity"”which is the opposite of the bright bursts in a typical pulsed laser. Despite its ominous name, the dark pulse laser is...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
