Science at the Timescale of the Electron

  • 01:10:54

Description

Ever since the invention of the laser over 50 years ago, scientists have been striving to create an x-ray version of the laser. Advances in extreme nonlinear optics now make it possible to efficiently upshift tabletop femtosecond lasers into the ultraviolet (EUV) and soft X-ray regions of the spectrum, to wavelengths as short as 8 Å. This unique high harmonic (HHG) light source is ideally suited for host applications in imaging and in understanding how advanced materials function. A host of applications in nanoscience and nanotechnology have now been demonstrated, including full-field microscopes with sub-wavelength spatial resolution in the soft X-ray region for the first time, quantifying how nanoscale energy flow differs from bulk, measuring how fast a material can change its electronic or magnetic state, probing how spin currents can control and enhance magnetization in ultra thin films, and visualizing the dynamic band structure of material and electron-electron interactions on sub-femtosecond timescales.
