Harnessing Extreme Quantum Light Science for understanding Quantum Materials
Most advanced applications of visible lasers require precise control over light – including the wavelength, polarization, waveform and coherence. However, until recently, there were no widely available coherent light sources at wavelengths shorter than the UV. Moreover, EUV and x-ray optics are expensive and challenging to manufacture, when available at all. The extreme quantum coherence of high harmonic (HHG) light sources is enabling exquisite control x-ray light using visible lasers - allowing full control over the waveform, polarization state, orbital and spin angular momenta, and divergence of HHG beams. Important applications include imaging and spectroscopy of quantum materials, as well as metrologies in support of next-generation nanotechnologies. A host of use cases in materials and nano science have now been demonstrated, including engineering energy flow in nanostructures, uncovering the microscopic mechanisms for manipulating the electronic or magnetic state of a material, and directly visualizing the dynamic band structure of materials on femtosecond time scales. Finally, the high spatial coherence of EUV sources makes it possible to implement diffraction-limited imaging at short wavelengths for the first time. This is paving the way for the development of commercial tools for EUV imaging that will provide easy access to these advanced techniques in the laboratory setting.

High Harmonic Generation with Structured Light Beams
We use intense vector beams to generate high harmonics or to create solenoidal currents in solids or gases.  We predict THz magnetic fields reaching the scale of those only available at user facilities.
