New method for better laser-material interaction

Using ultrashort laser pulses lasting a few picoseconds (trillionths of a second), Lawrence Livermore National Laboratory (LLNL) researchers have discovered an efficient mechanism for laser ablation (material removal) that ...

Polymer solar cells employing Forster resonance energy transfer

Two crucial tasks exist for realizing high-efficiency polymer solar cells: increasing the range of the spectral absorption of light and efficiently harvesting photo-generated excitons. In this work, Förster resonance energy ...

Quick-Change Molecules Caught in the Act

( -- The chemistry of life happens so fast that a millionth of a second is an eternity -- an eternity that is largely invisible to science. In that time, molecules change in ways we cannot see. Now, though, there ...

A picosecond is 10−12 of a second. That is one trillionth, or one millionth of one millionth of a second, or 0.000 000 000 001 seconds. A picosecond is to one second as one second is to 31,700 years.

The name is formed by the SI prefix pico and the SI unit second. It is abbreviated as ps.

One picosecond is equal to 1000 femtoseconds, or 1/1000 nanosecond. Because the next SI unit is 1000 times larger, measurements of 10−11 and 10−10 second are typically expressed as tens or hundreds of picoseconds. Some notable measurements in this range include:
