A Novel Few-Cycle Optical Source in the Mid-Infrared
In this thesis, I designed, simulated, and implemented a novel optical pulse generation system which is shown to be able to generate exceptionally short optical pulses in the mid-infrared, tunable from 2-4psm with pulse widths as low as 1.5 optical cycles at 3.5pum (18fs). Energies as high a 1pAJ were achieved, representing a peak power of roughly 100MW, at a 1kHz repetition rate, with excellen...
متن کاملDissociation and Ionization of Quasi-Periodically Vibrating H2+ in Intense Few-Cycle Mid-Infrared Laser Fields
Using quantum mechanics calculations, we theoretically study the dissociation and ionization dynamics of the hydrogen-molecule ion in strong laser fields. Having prepared the nuclear wave packet of H2+ in a specific vibrational state, a pump laser is used to produce a vibrational excitation, leading to quasi-periodical vibration without ionization. Then, a time-delayed few-cycle laser is applie...
متن کاملGeneration of isolated attosecond pulses in the far field by spatial filtering with an intense few-cycle mid-infrared laser
We report theoretical calculations of high-order harmonic generation (HHG) of Xe with the inclusion of multielectron effects and macroscopic propagation of the fundamental and harmonic fields in an ionizing medium. By using the time-frequency analysis we show that the reshaping of the fundamental laser field is responsible for the continuum structure in the HHG spectra. We further suggest a met...
متن کاملControlled polar asymmetry of few-cycle and intense mid-infrared pulses
We demonstrate synthesis of ultrabroadband and phase-locked two-color transients in the multiterahertz frequency range with amplitudes exceeding 13MV cm . Subcycle polar asymmetry of the electric field is adjusted by changing the relative phase between superposed fundamental and second harmonic components. The resultant broken symmetry of the field profile is directly resolved via electro-optic...
متن کاملFew-cycle driven relativistically oscillating plasma mirrors: a source of intense isolated attosecond pulses.
The conditions required for the production of isolated attosecond pulses from relativistically oscillating mirrors (ROM) are investigated numerically and experimentally. In simulations, carrier-envelope-phase-stabilized three-cycle pulses are found to be sufficient to produce isolated attosecond pulses, while two-cycle pulses will predominantly lead to isolated attosecond pulses even in the abs...
