Since the first demonstration of the laser in the 1960s, laser spectroscopy has become an essential tool for studying the detailed structures and dynamics of atoms and molecules. Advances in laser ...

The ultranarrow bandwidth mode-locked laser can be tuned for pulse duration. It uses a new filter configuration and single-walled carbon nanotube as saturable absorbers. The laser has a nearly ...

Scientists at the Stanford Linear Accelerator Center (SLAC) have devised a new way of creating twisted laser beams -- optical vortexes -- for carrying vast, near-infinite amounts of data down optical ...

It is challenging to generate ultrashort laser pulses at high powers, but repeatedly overlapping light pulses in a crystal can efficiently amplify a weak signal. Christoph Heyl is at the German ...

Orbiting high over the lunar surface is LADEE, the Lunar Atmosphere and Dust Environment Explorer, with a mission to probe the moon's exosphere and dust clouds. It will take readings using a number of ...
