General analytic solution for far-field phase and amplitude control, with a phase-only spatial light modulator.
Optics letters 39:7 (2014) 2137-2140
Abstract:
We present an analytical solution for the phase introduced by a phase-only spatial light modulator to generate far-field phase and amplitude distributions within a domain of interest. The solution is demonstrated experimentally and shown to enable excellent control of the far-field amplitude and phase.Quasi-phase-matched high-order harmonic generation using tunable pulse trains.
Optics express 22:7 (2014) 7722-7732
Abstract:
A simple technique for generating trains of ultrafast pulses is demonstrated in which the linear separation between pulses can be varied continuously over a wide range. These pulse trains are used to achieve tunable quasi-phase-matching of high harmonic generation over a range of harmonic orders up to the harmonic cut-off, resulting in enhancements of the harmonic intensity in excess of an order of magnitude. The peak enhancement of the harmonics is clearly shown to depend on the separation between pulses, as well as the number of pulses in the train, representing an easily tunable source of quasi-phase-matched high harmonic generation.Photoproduction of isolated photons, inclusively and with a jet, at HERA
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics 730 (2014) 293-301
Abstract:
The photoproduction of isolated photons, both inclusive and together with a jet, has been measured with the ZEUS detector at HERA using an integrated luminosity of 374 pb-1. Differential cross sections are presented in the isolated-photon transverse-energy and pseudorapidity ranges 6Laserwire: A high resolution non-invasive beam profiling diagnostic
