Attosecond light sources have enabled scientists to observe directly the dynamics of atoms and molecules on their natural length (+ngstrom) and time (sub-femtosecond) scales.

320 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 To understand the movements of electrons, and eventually those of subatomic particles, requires attaining the attosecond and ultimately zeptosecond (sextillionths of a second) range, Kaertner says. Achieving that requires pushing technology to produce pulses using higher-wavelength sources, and also producing pulses that encompass a wider range of frequencies — a more broadband source.

Leedle2, Yu Miao2, The timescale between 1 and 1,000 attoseconds (10–18 to 10–15 seconds), seemingly inconceivable on the level of ordinary experience, is highly significant in An attosecond is 1×10−18 of a second (one quintillionth of a second). For context, an attosecond is to a second what a second is to about 31.71 billion years.

Attosecond light sources have enabled scientists to observe directly the dynamics of atoms and molecules on their natural length (+ngstrom) and time (sub-femtosecond) scales. This frontier field has been called Attosecond Science, since the next smallest unit than a femtosecond is 1 attosecond (1 as) = 1/1,000,000,000,000,000,000 s.

The significantly faster electron dynamics, which are ultimately responsible for the following structural changes, occur on an attosecond (1 attosecond = 10 -18 seconds) timescale, and its study requires the use of attosecond laser pulses. 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. ized in an intense infrared laser ﬁeld [1] can be a potential source of attosecond pulses [2–4].

However, the duration 1 Introduction To resolve extremely fast events short light pulses are needed. In 2001 Paul and co-workers managed to create and for the rst time measure pulses shorter than one femtosecond (1 fs = 10 15 s), so called attosecond (1 as = 10 18 s) pulses [1]. With these pulses the possibility to do attosecond time-resolved measurements opened up. 1 Attosecond Science Research Team, RIKEN Center for Advanced Photonics, RIKEN, 2-1 Hirosawa, Wako, Saitama 3510198, Japan. 2 Department of Physics, Tokyo University of Science, 2641 Yamazaki, Noda, Chiba 278-8510, Japan.
