About these units
Attosecond (as)
An attosecond is 10⁻¹⁸ seconds, one quintillionth of a second. This unfathomably short interval is the domain of electron motion, where electrons shift orbitals, respond to electromagnetic stimuli, and perform quantum tunneling. Attosecond pulses—among the shortest ever created—enable direct observation of electron dynamics inside atoms. These technologies contribute to attosecond physics, a rapidly growing discipline that reveals quantum processes hidden from human intuition. At this scale, classical concepts of motion and time begin to lose meaning; quantum uncertainty and wavefunctions dominate. The attosecond is therefore not just a measurement but a gateway to the most fundamental processes in nature.
Picosecond (ps)
A picosecond equals 10⁻¹² seconds. At this timescale, even light travels only about 0.3 millimeters, making picoseconds vital in advanced optics, ultrafast laser systems, and femtochemistry. Picosecond lasers enable precision cutting in medical devices, microfabrication, and semiconductor processing. They also allow scientists to study vibrational modes of molecules and rapid electron transitions in materials. In telecommunications, picosecond precision is necessary for characterizing optical fiber dispersion, jitter, and photonic switching. At such rapid intervals, the boundaries of classical physics begin to blur, leading toward quantum mechanical interpretations of time and energy.
