    Controlling the photoelectron holography with shaped intense ultrashort laser pulses by Xiaoyun Zhao, Mingqing Liu, Wei-Chao Jiang, Weidong Li, Jing Chen, Xiaolei Hao

    Published 2024-02-01
    “…We perform a theoretical investigation on the control of photoelectron holography with shaped intense ultrashort laser pulses. By adjusting the π phase-flip position in the frequency domain, the shape of the time-dependent envelope of the input laser electric field changes from Gaussian to trapezoidal and finally to double-peak pulse. …”

    Self-waveguiding of relativistic laser pulses in neutral gas channels by L. Feder, B. Miao, J. E. Shrock, A. Goffin, H. M. Milchberg

    Published 2020-11-01
    “…We demonstrate that an ultrashort high intensity laser pulse can propagate for hundreds of Rayleigh ranges in a prepared neutral hydrogen channel by generating its own plasma waveguide as it propagates; the front of the pulse generates a waveguide that confines the rest of the pulse. …”

    Measuring enzyme binding using shaped ultrafast laser pulses by Weinacht T. C., Tseng C.-H., Pearson B. J.

    Published 2013-03-01
    “…We use multiphoton quantum-control spectroscopy to discriminate between enzyme-bound and unbound NADH (reduced nicotinamide adenine dinucleotide) molecules in solution. Shaped ultrafast laser pulses are used to illuminate both forms of NADH, and the ratio of the fluorescence from the bound and unbound molecules for different pulse shapes allows us to measure binding without spectrally resolving the emitted fluorescence or relying on the absolute fluorescence yield. …”
