Optimization of attosecond pulse generation.
The generation of attosecond pulses by superposition of high harmonics relies on their synchronization in the emission. Our experiments in the low-order, plateau, and cutoff regions of the spectrum reveal different regimes in the electron dynamics determining the synchronization quality. The shortest pulses are obtained by combining a spectral filtering of harmonics from the end of the plateau ...
متن کاملSingle isolated attosecond pulse from multicycle lasers.
We propose a new experimental scheme to produce clean isolated pulses lasting a few hundreds of attoseconds. It is based on high harmonics generation and uses the polarization gating technique combined with the ionization dynamics and the spatial filtering provided by the three-dimensional field propagation. The proposed method is easy to implement, robust against laser parameter fluctuations, ...
متن کاملIntegrating solids and gases for attosecond pulse generation
Control of the field of few-cycle optical pulses has had an enormous impact on attosecond science. Subcycle pulses open the potential for non-adiabatic phase matching while concentrating the electric field so it can be used most efficiently. However, subcycle field transients have been difficult to generate. We exploit the perturbative response of a sub-100 μm thick monocrystalline quartz plate...
متن کاملRelativistic Nonlinear Thomson Scattering: Toward Intense Attosecond Pulse
Over many millennia of human history, mankind has been interested in how events change in time, namely their dynamics. However, the time resolution of recording individual steps has been limited to direct sensory perception such as the eye’s ability (0.1 sec. or so) to recognize the motion, until 1800 AD when the technical revolution occurred following the industrial revolution. A famous motion...
متن کاملOptimization of three-color laser field for the generation of single ultrashort attosecond pulse.
We present an efficient and realizable scheme for the generation of an ultrashort single attosecond (as) pulse. The feasibility of such a scheme is demonstrated by solving accurately the time-dependent Schrödinger equation using the time-dependent generalized pseudospectral (TDGPS) method. This scheme involves the use of the optimization of the three-color laser fields. The optimized laser puls...
