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 ...

Studies on the molecular dynamics of polymers in solution often use longer time scales due to the size of the macromolecules being studied. To fully elucidate the complete dynamics and interactions of polymers in solution, however, it is necessary to also study the ultrafast (sub-picosecond) dynamics as well. In this paper, a KMLabs by Brad Sohnlein

With the increase in integrated photonics careers, it is essential that students in undergraduate institutions gain experience with equipment, techniques, and ideas used in the field.  In this paper, an upper level undergraduate lab is designed utilizing a KMLabs by Brad Sohnlein

3D pulsed laser atom probe tomography (APT)  is an atomic scale materials characterization and 3D imaging method utilizing ultrafast pulses to induce photon assisted field ion evaporation in certain materials. Currently, modern APT measurements employ coherent, pulsed near ultraviolet (NUV) light to induce the field ion evaporation ...
