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. The word "attosecond" is formed by the prefix atto and the unit second. Atto-was derived from the Danish word for eighteen (atten). Its symbol is as.

To implement attosecond time resolution using TEM and a continuous-wave laser, the researchers placed a thin dielectric membrane at the intersection of the laser and electron beam, via an access port that would usually hold the TEM's condenser aperture.

IMAGE: Strong driving pulse E0 generates high order harmonics every half optical cycle of In this work, we investigate with attosecond time resolution the changes induced by the vibrational motion on the potential barrier that sustains the 3 σ g − 1 shape resonance in N 2. We do so by ionizing the molecule with extreme ultraviolet (XUV) radiation consisting of high-order harmonics spanning an energy range between 20 and 40 eV The advent of attosecond (1 as = 1 0 − 1 8 s) metrology is finally allowing researchers to probe electron ionization dynamics in real time. Attosecond experiments have revealed that the photoionization of electrons occurs with measurable delays in atomic gases [ 2 , 3 ] and solids [ 4 , 5 ]. The attosecond pulse structure is shorter than the response time of any detector or electronic device, but it is possible to obtain temporal information about attosecond photoionization indirectly by investigating coherent cross-correlation photoelectron spectrograms between the attosecond pulse and a weak IR laser probe.

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.

The attosecond pulse structure is shorter than the response time of any detector or electronic device, but it is possible to obtain temporal information about attosecond photoionization indirectly by investigating coherent cross-correlation photoelectron spectrograms between the attosecond pulse and a weak IR laser probe.

Electronic motion is a key process in a wide range of modern technologies, including micro- to nano-electronics, photovoltaics, bioinformatics, molecular biology, and medical as well as information technologies. The atomic-scale motion of electrons typically unfolds within tens to thousands of attoseconds (1 attosecond [as] = 10-18 s). Recent advances in laser science have opened the door to Timing jitter characterization of optical pulse trains from free-running mode-locked lasers with attosecond resolution is demonstrated using balanced optical cross correlation in the timing detector and the timing delay configurations. In the timing detector configuration, the balanced cross correlation between two mode-locked lasers synchronized by a low-bandwidth phase-locked loop is used to Probing Single-Photon Ionization on the Attosecond Time Scale K.
