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 of applications in imaging and understanding how advanced materials function. A host of applications in nanoscience and nanotechnology have now been demonstrated using EUV HHG, including full-field microscopes with record 14nm spatial resolution, 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.

Speakers:

Margaret Murnane, Professor in Physics, ECE and Materials at the University of Colorado.

Joe d’Angelo, (Moderator), Executive Publisher.
