The Attosecond Lighthouse in Gas: Isolated Attosecond Pulses generation and Physical Dynamic probing
نویسندگان
چکیده
Through high-harmonic generation, attosecond pulse train can be produced with half-cycle temporal separation. Each pulse in this train carries information on physical processes in the medium during its generating time. Here, the spatially chirped laser pulses are used in high-order harmonics generation experiment to get a train of isolated attosecond pulses angularly separated—an attosecond lighthouse [1]. It is easy to reach each single attosecond pulse and record the whole physical information with subfemtosecond resolution.

Numerical Simulation of an Intense Isolated Attosecond Pulse by a Chirped Two-Color Laser Field
We investigate theoretically the high-order harmonic spectrum extension and numerical generation of an intense isolated attosecond pulse from He+ ion irradiated by a two-color laser field. Our simulation results show that the chirp of the fundamental field can control HHG cutoff position. Also, these results show that the envelope forms of two fields are important factors for controlling the re...
متن کاملAttosecond lighthouse driven by sub-two-cycle, 1.8 μm laser pulses
We generate space-time coupled attosecond pulse trains with a 1.8 μm wavelength laser pulse using the ‘attosecond lighthouse’ technique. We show low divergence, spatially well-separated beamlets from low ionization potential gas media. We also find that there is little long trajectory contribution—only the short trajectory contribution is clearly visible for any beamlet. These results open a ne...
متن کاملIsolation of attosecond pulses from the attosecond lighthouse
This paper proposes and verifies methods to improve the isolation of the attosecond pulses generated via the attosecond lighthouse technique in gases. We find that the converging fundamental field can compensate for the inherent diverging wavefront of the attosecond pulses, but is only valid over a limited portion of the spectrum and sacrifices the maximum attainable photon energy. We discuss t...

We numerically demonstrate the generation of intense, low-divergence soft X-ray isolated attosecond pulses in a gas-filled hollow waveguide using synthesized few-cycle two-color laser waveforms. The waveform is a superposition of a fundamental and its second harmonic optimized such that highest harmonic yields are emitted from each atom. We then optimize the gas pressure and the length and radi...
متن کاملAttosecond pulses measured from the attosecond lighthouse
The attosecond lighthouse is a method of using ultrafast wavefront rotation with high-harmonic generation to create a series of coherent, spatially separated attosecond pulses. Previously, temporal measurements by photoelectron streaking characterized isolated attosecond pulses created by manipulating the single-atom response1–4. The attosecond lighthouse, in contrast, generates a series of pul...
