A team of astronomers at the Center for Astrophysics | Harvard & Smithsonian has identified a giant, near-spherical void ...

Ultrashort mid-infrared (mid-IR) laser pulses are essential for applications such as molecular spectroscopy, nonlinear microscopy, and biomedical ...

A compact fiber-based system has been developed to compress mid-infrared laser pulses to 187 femtoseconds using low input power. By integrating a holmium-doped ZBLAN photonic crystal fiber within a ...

Scientists from Germany, Japan, and India have demonstrated that femtosecond laser pulses can force an entire layer of molecules to rotate in unison on a two-dimensional quantum material, a result ...

Born in Brooklyn in 1942, Freed’s scientific trajectory began early; he and his brother Jack, who himself would go on to ...
