In this paper, the authors review the development and application of coherent short wavelength light sources implemented using the high harmonic generation (HHG) process, such as the KMLabs by Brad Sohnlein

Ultrathin films and multilayers, with controlled thickness down to single atomic layers, are critical for advanced technologies ranging from nanoelectronics to spintronics to quantum devices. However, for thicknesses less than 10 nm, surfaces and dopants contribute significantly to the film properties, ...

The vacuum ultraviolet (VUV) spectral region, covering approximately 6–15 eV, has a unique ability to probe physical and chemical processes.  This range of the electromagnetic spectrum is often used as an ionization source in angle-resolved photoelectron spectroscopy (ARPES) and photoionization mass spectrometry (PIMS), or to initiate ...

Prof. Margaret Murnane, Physics, fellow, JILA, University of Colorado, Boulder

KMLabs co-founder Murnane's lecture is about tabletop X-ray lasers. Ever since the invention of the laser, 50 years ago, researchers have also tried to develop lasers for X-rays. The aim is to ...

We implement coherent diffractive imaging (CDI) using a phase-matched high-harmonic generation (HHG) source at 13 nm, demonstrating reconstructed images with a record 22 nm resolution for any tabletop, light-based microscope. We also demonstrate the first reflection-mode CDI using a compact extreme ultraviolet (EUV) source, achieving ...

High-resolution imaging is an invaluable tool for understanding nanoscale systems. In particular, tabletop extreme ultraviolet (EUV) coherent diffractive imaging (CDI) techniques based on high harmonic generation (HHG) can combine femtosecond (fs) pulse durations with nanometer resolution and elemental-, spin-, electronic-and ...

High-resolution imaging is an essential tool for understanding nanoscale systems. In particular, tabletop extreme ultraviolet (EUV) coherent diffractive imaging (CDI) techniques based on high harmonic generation (HHG) are ideal for investigating complex nanostructured systems, including their ...
