formation of attosecond pulses is one thing; to prove that it does is quite another matter, and this was the main accomplishment of the two aforementioned papers published in 2001 [2, 3]. 1.2.1 Attosecond Pulse Trains and Isolated Attosecond Pulses According to the three-step model, the attosecond pulse formation will occur twice

The use of machine learning helped to improve The researchers directed an attosecond-long, extremely ultraviolet (XUV) light pulse onto a helium atom to excite the electrons. At the same time, they fired a second infrared laser pulse at the Attosecond interferometry in time-energy domain The space-momentum domain interferometer is a key technique in modern precision measurements, and has been widely used for applications that require The new method allowed to push this limitation down to 12 attoseconds (1.2 x 10-17 s, 1/200 of the wavelength), which surpasses the atomic unit of time (24 attoseconds) by a factor of two. As the To realize the attosecond-pump/attosecond-probe measurement, however, an intense attosecond pulse is required to achieve a focal intensity larger than 10 14 W/cm 2 (19 – 21). In the new research Following the discovery of attosecond laser pulses, about a decade ago, attosecond science has developed into a vibrant, new research field, where the motion of single or multiple electrons and, in molecules, the coupling of electronic and nuclear motion, can be investigated, on attosecond to few-femtosecond timescales. An attosecond is a millionth of a picosecond, or 10 −18 of a second. Light travels 0.3 nanometers in an attosecond, which is roughly the spacing between atoms in a solid.
