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, ...

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

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 ...

Read NowThe maximum photon energy achievable in high harmonic generation is proportional to the square of the excitation wavelength. Due to this scaling, extreme ultraviolet (XUV) light generation requires intense infrared pulses as the excitation wavelength. Converting ultrafast pulses from Ti:sapphire to longer wavelengths through optical parametric ...
