Thermal wave packets induced by attosecond laser pulses
نویسندگان
چکیده
In this paper the dynamics of the interaction of attosecond laser pulses with matter is investigated. It will be shown that the master equation: modified Klein-Gordon equation describes the propagation of the heatons. Heatons are the thermal wave packets. When the duration of the laser pulses ∆t is of the order of attosecond the heatonthermal wave packets are nondispersive objects. For ∆t → ∞ the heatons are damped with damping factor of the order of relaxation time for thermal processes.

Attosecond control of ionization by wave-packet interference.
A train of attosecond pulses, synchronized to an infrared (IR) laser field, is used to create a series of electron wave packets (EWPs) that are below the ionization threshold in .helium. The ionization probability is found to strongly oscillate with the delay between the IR and attosecond fields twice per IR laser cycle. Calculations that reproduce the experimental results demonstrate that this...
متن کاملAmplitude and phase spectroscopy of attosecond electron wave packets
Synopsis: The interference of attosecond electron wavepackets, created by high harmonic and femtosecond laser pulses, is measured. The first electron wavepacket is generated by direct ionization of He, and the second one by the two step process of resonant excitation by the attosecond high harmonic pulse and subsequent ionization by the laser pulse. The amplitude and phase retrieved from the in...
متن کاملNanoscience with Attosecond Laser Pulses
In this paper the interaction of attosecond laser pulses with matter is investigated. The scattering and potential motion of heat carriers as well as the external force are considered. Depending on the ratio of the scatterings and potential motion the heat transport is described by the thermal forced Klein-Gordon or thermal modified telegraph equation. For thermal Heisenberg type relation V τ ∼...
متن کاملCoherent control of electron wave packets in dissociating H + 2
Coherent control of electron localization in the dissociation of a hydrogen molecular ion exposed to an attosecond pulse train and a time-delayed near-infrared laser pulse are studied by solving numerically the time-dependent Schrödinger equation. The attosecond pulses in the train generate a train of electron wave packets in the dissociating molecular ion, which are steered by the near-infrare...
متن کاملNuclear collective processes study with attosecond laser pulses
In this paper the possibility of the excitation of collective nuclear motion with attosecond laser pulses is investigated. Following the results of our earlier results (Lasers in Engineering, 11 (2001), p. 259) the hyperbolic heat transport for nuclear matter is formulated and solved. It is shown that in the vicinity of the 30 MeV excitation energy the recollided electrons can excite the giant ...
