An attosecond is to a second, as a second is to approximately 31.69 billion years. [2] The attosecond is a tiny unit but it has various potential applications: it can observe oscillating molecules, the chemical bonds formed by atoms in chemical reactions, and other extremely tiny and extremely fast things.
A femtosecond is a unit of time in the International System of Units (SI) equal to 10 −15 or 1 ⁄ 1 000 000 000 000 000 of a second; that is, one quadrillionth, or one millionth of one billionth, of a second. [1] A femtosecond is to a second, as a second is to approximately 31.69 million years.
attosecond: 10 −18 s: One quintillionth of a second. femtosecond: 10 −15 s: One quadrillionth of a second. Pulse time on fastest lasers. svedberg: 10 −13 s: Time unit used for sedimentation rates (usually of proteins). picosecond: 10 −12 s: One trillionth of a second. nanosecond: 10 −9 s: One billionth of a second. Time for molecules ...
High harmonic generation in krypton.This technology is one of the most used techniques to generate attosecond bursts of light. Attosecond physics, also known as attophysics, or more generally attosecond science, is a branch of physics that deals with light-matter interaction phenomena wherein attosecond (10 −18 s) photon pulses are used to unravel dynamical processes in matter with ...
Femtochemistry is the area of physical chemistry that studies chemical reactions on extremely short timescales (approximately 10 −15 seconds or one femtosecond, hence the name) in order to study the very act of atoms within molecules (reactants) rearranging themselves to form new molecules (products).
A saturable absorber is an optical device that exhibits an intensity-dependent transmission, meaning that the device behaves differently depending on the intensity of the light passing through it. For passive mode locking, ideally a saturable absorber selectively absorbs low-intensity light, but transmits light of sufficiently high intensity.
The Draw-A-Scientist Test (DAST) is an open-ended projective test designed to investigate children's perceptions of the scientist. Originally developed by David Wade Chambers in 1983, the main purpose was to learn at what age the well known stereotypic image of the scientist first appeared.
