Combined visible and near-infrared OPA for wavelength scaling experiments in strong-field physics
David T. Lloyd, Kevin O'Keeffe, Adam S. Wyatt +3
We report the operation of an optical parametric amplifier (OPA) capable of producing gigawatt peak-power laser pulses with tunable wavelength in either the visible or near-infrare…
Gaussian-Schell analysis of the transverse spatial properties of high-harmonic beams
David T. Lloyd, Kevin O'Keeffe, Patrick N. Anderson +1
High harmonic generation (HHG) is an established means of producing coherent, short wavelength, ultrafast pulses from a compact set-up. Table-top high-harmonic sources are increasi…
Complete spatial characterization of an optical wavefront using a variable-separation pinhole pair
David T. Lloyd, Kevin O'Keeffe, Simon M. Hooker
We present a technique for measuring the transverse spatial properties of an optical wavefront. Intensity and phase profiles are recovered by analysis of a series of interference p…
Quasi-phase-matching of high-order-harmonic generation using polarization beating in optical waveguides
Lewis Z. Liu, Kevin O'Keeffe, Simon M. Hooker
A scheme for quasi-phase-matching high-harmonic generation is proposed in which polarization beating within a hollow core birefringent waveguide modulates the generation of harmoni…
Optical Rotation Quasi-Phase-Matching for Circularly Polarized High Harmonic Generation
Lewis Z. Liu, Kevin O'Keeffe, Simon M. Hooker
The first scheme for quasi-phase-matching high harmonic generation of circularly polarized radiation is proposed: optical rotation quasi-phase-matching (ORQPM). In ORQPM propagatio…
Quasi-phase-matching of high-order-harmonic generation using multimode polarization beating
Lewis Z. Liu, Kevin O'Keeffe, Simon M. Hooker
The generalization of quasi-phase-matching using polarization beating and of multimode quasi-phase-matching (MMQPM) for the generation of high-order harmonics is explored, and a me…
