Some electrons will gain a boost in energy from the modulation, while others will lose energy. Figure. Controlling X-ray light using laser light. By changing the color, polarization and phase of the femtosecond laser beam, the spectrum, pulse duration, polarization, phase and shape of the generated short wavelength HHG beam can be controlled—on exquisite sub-Å and sub-attosecond (10-18 s) length and time scales.

: one quintillionth (10−18) of a second An attosecond is to a second what a second is to the age of the universe. — IEEE Spectrum. An attosecond ( as) is a very short period of time. It is equal to one quintillionth of a second (or 0.000000000000000001 seconds). It can also be written as 10−18 seconds. An attosecond is one quintillionth (10 -18) of a second and is a term used in photon research.

Just as femtosecond pulses allow the observation of the motion of atoms in molecules, attosecond pulses will allow us to trace electronic motion and electronic relaxation (such as inner-shell dynamics) in atoms and molecules. In addition, attosecond science will have strong, phased laser fields perfectly synchronized with the attosecond pulse.

Attosecond pulses are produced in a process called high-order harmonic generation, in which a short, intense laser pulse interacts with atoms or molecules in a highly nonlinear process, leading to the generation of high-order frequencies of the fundamental laser with a large spectral bandwidth, supporting pulses with attosecond duration.
