About the cover
(JILA Light+Matter 2023/ Nature Nano 2023):
The Swirling Spins of Hedgehogs. Experimental schematic of 3D soft x-ray vector ptychography. The left side of the image shows the lasers probing the metal superlattice.
About the cover
(SPIE Press 2023):
“Coherent EUV light sources based on high-order harmonic generation: Principles and applications in nanotechnology,” Chapter 21 in the book "Photon Sources for Lithography and Metrology," V. Bakshi, Ed., SPIE Press, Bellingham, Washington, pp. 847–909. ISBN: 9781510653719 (2023).
About the cover
(ACS Photonics 2022):
An ultrafast vortex pulse carrying spatiotemporal orbital angular momentum is measured to reveal its pulse dispersion, beam divergence, and topological charges in space-time.
About the cover
(Science 2018):
COVER Illustration of a pair of time-delayed vortex laser pulses (red) being coherently up-converted into extreme ultraviolet (EUV) vortex pulses (cyan) that possess self-torque. This property manifests as a smooth, temporal increase in orbital angular momentum (OAM) (represented by the frequency of spatial twists in the EUV beam), progressing from low OAM (top right) to high OAM (bottom left).
