New record: 3-D-printed optical-electronic integration

Optoelectronic integration offers a promising strategy to simultaneously obtain the merits of electrons and photons when they serve as information carriers, including high-density communication and high-speed information ...

Shooting movies in atoms

Researchers of the Laboratory for Attosecond Physics at LMU and the Max Planck Institute for Quantum Optics have developed a microscope that tracks the motion of electrons.

Transformation through light

Laser physicists have taken snapshots of how C60 carbon molecules react to extremely short pulses of intense infrared light.

What really happens at femtosecond junctions?

When beams of ultra-short laser pulses running in the same direction intersect with each other at a noticeable angle, various interactions occur between the pulses. These physical phenomena are complicated, and their mathematical ...

A femtosecond is the SI unit of time equal to 10-15 of a second. That is one quadrillionth, or one millionth of one billionth of a second. For context, a femtosecond is to a second what a second is to about 31.7 million years.

The word femtosecond is formed by the SI prefix femto and the SI unit second. Its symbol is fs.

A femtosecond is equal to 1000 attoseconds, or 1/1000 picosecond. Because the next higher SI unit is 1000 times larger, times of 10-14 and 10-13 seconds are typically expressed as tens or hundreds of femtoseconds.
