LIGHT travelling through a solid has been stopped in its tracks for more than a second. This is a thousand times longer than the previous record set in gases. To stop light in a gas, physicists use a ...

A team at the University of Otago created a non-contact gigahertz antenna that uses an enclosed vapor cell of excited rubidium atoms with laser beams for sensing their state. The underlying ...

Two independent teams of physicists have overcome the restless nature of light and stopped laser pulses in their tracks. A proposed method, now in tests by a third team, may even make light pulses ...

With the high-power LPL BF98-40-5 laser bar, Osram has optimized the chip design in terms of beam quality. With the high-power LPL BF98-40-5 laser bar, Osram has optimized the chip design in terms of ...
