The laser, built for fusion research, has already shown the ability to fire 4 megajoules of infrared energy for up to 20 nanoseconds.
«The hot electrons gave off their energy after several nanoseconds instead of some hundred femtoseconds.
When the electron released its new energy, it was exactly the right amount needed to bump the nucleus to a higher energy state for about 1.9 nanoseconds, they report in the 28 August Physical Review Letters.
Powerful lasers can therefore be used as microscopes to explore, during few nanoseconds, the high - energy radiation processes occurring in astrophysical objects from regions largely unresolved by the most powerful telescopes.
High - energy dogs thrive moving at breakneck speeds and can literally go from 0 — 100mph in a nanosecond.
Almost immediately (nanoseconds) they relax from their excited state by either 1) emitting that energy as a new photon, some of which will continue up towards space, some of which will go back downward to be reabsorbed, thus keeping the energy in the atmosphere longer, or 2) by colliding with another gas molecule, most likely an O2 (oxygen) or N2 (nitrogen) molecule since they make up over 98 % of the atmosphere, thereby converting the extra vibrational energy into kinetic energy by transferring it to the other gas molecule, which will then collide with other molecules, and so on, making the air warmer.
There is collision every nanosecond but no energy is lost So the velocity of air molecules are about 400 m / s.
Air molecule is excellent conductor to itself - the molecule velocities are «transferred» at 100 % effectively in less than nanosecond, but the only way energy through air is «conducted» is via air packets - or air doesn't conduct to itself, it transfers heat from one location to another via movement of air molecules - convection.
Or the energy of the kinetic gas is forward, backward, upward, downward, left, and right and this changing every nanosecond.
Terrestrial radiation absorbed by CO2 is immediately thermalized, i.e. the radiant energy absorbed by CO2 molecules is immediately (about 0.1 nanosecond) transferred (in a process similar to thermal conduction) to other atmospheric molecules which outnumber CO2 molecules 2500 to 1.
The time interval between molecular colliwsions is a few nanoseconds; but the lifetimes of the excited states, can be microseconds to milliseconds; so the energy is lost in collisions, before the molecule gets a chance to re-radiate.
