Since the beginning of 2010, there has been a study of electrons’ movement in atoms and molecules that are so rapid and measured in attoseconds. An attosecond is a study to represent the time frame it takes for the light to travel the length of two hydrogen atoms. Also, as a unit of attosecond – 10^-18 of a second – is to one second as one second is to the universe’s age, according to Johan Jarnestad (2023). That indicates that light can circle the Earth 7.5 times in a single second, but in an attosecond, light barely moves from one end of a molecule to the other. In 2019, became an SI unit formed by the prefix atto and the unit second, derived from the Danish word for eighteen (atten). Example includes the ionization and recollision of an electron from its parent atom or molecule. Finally, the goal is to observe and control ultra-fast electron motion on the natural atomic timescale. However, even though it has been discovered and the methods can capture the extremely rapid processes inside atoms and molecules, what is special about laser light?
