Creating the Broadest Spectral, Coherent-light Source with High-harmonic Generation

For the first time, researchers have produced a coherent, laser-like, directed beam of light that simultaneously streams ultraviolet light, X-rays and all wavelengths in between (see video). One of the few light sources to successfully produce a coherent beam that includes X-rays, this new technology is the first to do so using a setup that fits on a laboratory table. moreApr. 17, 2012

Newport’s WEU-02 Wavelength Extension Unit for Multimodal Imaging

Newport's WEU-02 wavelength extension unit is designed to expand the capability of femtosecond lasers. Through a series of user controls, the WEU-02 can be configured for use in various spectroscopy, imaging, and pump-probe applications. It can also be integrated into two-photon microscope set-ups to add modalities for enhanced imaging capabilities. moreJan. 17, 2012

Optical Flywheel Enables Slow-motion Pictures of Atoms and Molecules

The world's most accurate metronome keeps stroke to an incredible 10 quintillionth of a second. The device enables slow-motion pictures from the world of molecules and atoms, scientists from the Center for Free-Electron Laser Science (CFEL) in Hamburg, Germany, and the Massachusetts Institute of Technology (MIT) report. The metronome, an ultrashort pulse laser, acting as an optical flywheel, is currently the most precise clock generator on short time scales, writes the research team headed by DESY scientist Prof. Franz X. more
