About this event


JILA (U. Colorado & NIST) 


Ever since the invention of the laser 50 years ago, scientists have been striving to extend coherent laser-like beams into the X-ray region of the spectrum.  Very recently, we used tabletop femtosecond lasers to create bright beams of X-rays at wavelengths <1 nm, by harnessing a new ability to manipulate electrons on their natural, attosecond (10-18 s), time-scales[1].    Ultrafast X-rays are powerful probes of the nanoworld.  They penetrate thick samples and can image small objects.  This talk will also highlight how ultrafast X-rays can capture the coupled motions of charges, spins, phonons, and photons that underlie function in nanosystems on the fastest timescales.  Experiences regarding technology transfer can also be discussed.
