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. 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.
