متن کاملAbsorption and emission of single attosecond light pulses in an autoionizing gaseous medium dressed by a time-delayed control field
An extreme ultraviolet (EUV) single attosecond pulse passing through a laser-dressed dense gas is studied theoretically. The weak EUV pulse pumps the helium gas from the ground state to the 2s2p(1P ) autoionizing state, which is coupled to the 2s2(1S) autoionizing state by a femtosecond infrared laser with the intensity in the order of 1012 W/cm2. The simulation shows how the transient absorpti...
متن کاملSubcycle ac stark shift of helium excited states probed with isolated attosecond pulses.
Recent advances in attosecond science have relied upon the nearly instantaneous response of free electrons to an external field. However, it is still not clear whether bound electrons are able to rearrange on sublaser cycle time scales. Here, we probe the optical Stark shifts induced by a few-cycle near infrared laser field in helium bound states using isolated attosecond pulses in a transient ...
متن کاملAttosecond Transient Absorption Spectroscopy
Motion in the microcosm unfolds via the formation of wavepackets, resulting from a coherent superposition of quantum states. Pioneered by A. H. Zewail, nuclear motion in (bio-)molecules as well as the formation and rupture of chemical bonds have been accessed extensively by femtosecond (1 fs = 10 seconds) pump-probe spectroscopy. For these outstanding experiments, A. H. Zewail was awarded the N...
متن کاملAttosecond Metrology and Spectroscopy
The origin of attosecond metrology is linked to the advent of ultrashort mode locked laser sources femtosecond lasers, chirped pulse amplification, carrier-envelope-phase stabilization and the technological aspects of this development that rendered experiments with a temporal resolution of tens of attoseconds possible. The high-order harmonicgeneration process yields laser pulses in the wavelen...
