Circularly Polarized Attosecond Pulses Enabled by an Azimuthal Phase and Polarization Grating Open
[EN]High-harmonic generation (HHG) is an extreme nonlinear optical process that can map the properties of an infrared driving laser beam onto short wavelength attosecond pulse trains. However, current techniques for generating circularly p…
Robust broadband ptychography algorithms for high-harmonic soft X-ray supercontinua Open
We demonstrate PaCMAN, a ptychography algorithm that can reconstruct high quality images with broadband illumination sources while being robust to shot, detector, and parasitic noise. We extend prior monochromatization work to improve accu…

Angular distribution of electron emission from ultrafast nanotip sources Open
We investigate the angular distribution of ultrafast laser-induced electron emission from a tungsten nanotip in the multiphoton regime. A theoretical model allows precise determination of the relative contribution of different electron emi…
High-fidelity ptychographic imaging of highly periodic structures enabled by vortex high harmonic beams Open
Ptychographic coherent diffractive imaging enables diffraction-limited imaging of nanoscale structures at extreme ultraviolet and x-ray wavelengths, where high-quality image-forming optics are not available. However, its reliance on a set …

Temporal and spectral multiplexing for EUV multibeam ptychography with a high harmonic light source Open
We demonstrate temporally multiplexed multibeam ptychography implemented for the first time in the EUV, by using a high harmonic based light source. This allows for simultaneous imaging of different sample areas, or of the same area at dif…
Necklace-structured high-harmonic generation for low-divergence, soft x-ray harmonic combs with tunable line spacing Open
The extreme nonlinear optical process of high-harmonic generation (HHG) makes it possible to map the properties of a laser beam onto a radiating electron wave function and, in turn, onto the emitted x-ray light. Bright HHG beams typically …
