Recent developments of ultrashort intense light sources operating in the XUV and X-ray spectral regions promise to revolutionize chemistry, as they will give access to dynamical processes occurring in the attosecond time scale (1 asec = 10-18 s), the natural time scale for electronic motion in … 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 to a train of attosecond pulses with a 450 as duration, was focused by a toroidal mirror into the sensitive region of a magnetic bottle electron spectrometer containing a diffu-sive Ar gas jet. 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.

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.

To measure and control these dynamics therefore requires ultrafast sources of radiation combined with efficient detection techniques. The realiza-tion of extreme ultraviolet (XUV) attosecond (1as 10 18 s) pulses [1,2] has, for the first time, made direct measurements of electron dynamics possible [3–5]. Recent developments of ultrashort intense light sources operating in the XUV and X-ray spectral regions promise to revolutionize chemistry, as they will give access to dynamical processes occurring in the attosecond time scale (1 asec = 10-18 s), the natural time scale for electronic motion in atoms and molecules.

The addition of a weak IR pulse allows for additional phase control. 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.
