In the race towards attosecond (as) pulses for which high order harmonics generated in rare gases are the best candidates, both the Harmonic spectral range and spectral phase have to be controlled. We present in this proceeding four mirrors numerically optimized and designed to compensate for the...
In the terminology of adaptive optics, a large number of studies involving the control of nonlinear optical phenomena have been reported. The key concept in such works is the implementation of an artificial design in the distributions of amplitude, phase, or polarization of the incident light to ...
Ultrashort pulses available at modern light sources, provides new opportunities to study and control ultrafast electronic-nuclear motions in molecules on their natural time scales1,2,3. Moreover, the few-cycle attosecond laser pulses with carrier-envelope-phase (CEP) open the possibilities to capture...
For the output pulse train, only the change in this phase value modulo 2π is relevant. This can very sensitively depend on factors such as the laser power, resonator alignment, etc. carrier–envelope Offset Frequency The carrier–envelope offset frequency (CEO frequency) of a mode-locked ...
We present a phase-reconstruction algorithm for a self-referenced spectrographic pulse characterization technique called "very advanced method for phase and intensity retrieval of e-fields" (VAMPIRE). This technique permits a spectral phase reconstruction of pulses with separated frequency components. The ...
We provide a brief review of how phase space techniques are explored within strong-field and attosecond science. This includes a broad overview of the exis
spectral information, the combined application of spectral interferometry and CEP control allows the measurement of otherwise inseparable temporal events on an attosecond time scale. As a specific example, we apply this general method to the case of attosecond pulse train generation, where it allows ...
