*Title of Talk:*

/“Science at the Timescale of the Electron: Ultrafast X-Rays and 
Applications”/

*Abstract:*

Ever since the invention of the laser over 50 years ago, scientists have 
been striving to create an x-ray version of the laser. The x-ray sources 
we currently use in medicine, security screening, and science are in 
essence the same x-ray light bulb source that Röntgen discovered in 
1895. In the same way that visible lasers can concentrate light energy 
far better than a light bulb, a directed beam of x-rays would have many 
useful applications in science and technology. The problem was that 
until recently, we needed ridiculously high power levels to make an 
x-ray laser. The first successful x-ray laser experiments were, in fact, 
powered by nuclear detonations as as part of the “star wars” program in 
the 1980s. To make a practical, tabletop-scale, x-ray laser source 
required taking a very different approach that involves transforming a 
beam of light from a visible laser into a beam of x-rays. The story 
behind how this happened is surprising and beautiful, highlighting how 
powerful our ability is to manipulate nature at a quantum level. Along 
the way, we also learned to generate the shortest strobe light in 
existence - fast enough to capture even the fleeting dance of electrons 
in the nanoworld. This new capability shows promise for 
next-generation electronics, data and energy storage devices, and future 
medical diagnostics. /(Popmintchev et al, Science 336, 1287 (2012))/
