Since the first demonstration of the generation of attosecond pulses (1 as= 10− 18 s) in the
extreme-ultraviolet spectral region, several measurement techniques have been introduced …

The generation of extremely short isolated attosecond pulses requires both a broad spectral
bandwidth and control of the spectral phase. Rapid progress has been made in both …

Attosecond transient absorption is one of the promising new techniques being developed to
exploit the availability of sub-femtosecond extreme ultraviolet (XUV) pulses to study the …

The broad bandwidth of an isolated attosecond pulse excites a vast number of states
simultaneously, and the corresponding absorption features can be monitored with …

An attosecond pulse is used to create a wavepacket in molecular nitrogen composed of
multiple bound and autoionizing electronic states of Rydberg and valence character …

Electronic wavepackets composed of multiple bound excited states of atomic neon lying
between 19.6 and 21.5 eV are launched using an isolated attosecond pulse. Individual …

Noncollinear four-wave-mixing (FWM) techniques at near-infrared (NIR), visible, and
ultraviolet frequencies have been widely used to map vibrational and electronic couplings …

Progress in high-harmonic generation has led to high-energy attosecond pulses with cutoff
above the carbon 1 s edge (283.8 eV). These pulses are essential to extend time-resolved …

We present theoretical simulations of the attosecond transient absorption of singly-excited
states of helium atoms in the presence of a dressing near-infrared or infrared laser. In …

We present a theoretical study of the delay-dependent Autler-Townes (AT) splitting in
transient absorption spectroscopy of an isolated attosecond pulse in helium atoms subject to …
