A team of researchers at the University of Colorado at Boulder has taken another step in the quest to build a compact, tabletop x-ray microscope that could be used for biological imaging at super-high resolution.
By firing a femtosecond laser - a laser that generates light pulses with durations as short as 100 trillionth of a second - through a gas-filled tube called a waveguide, they were able to create more efficient "laser-like" beams in regions of the spectrum that were previously inaccessible.
The wavelength region over which they generate this "soft" x-ray light efficiently is called the "water-window" region, an important region for biological imaging, according to physics Professor Margaret Murnane. She also is a fellow of JILA, a joint institute of CU-Boulder and the National Institute of Standards and Technology.
