Peering into plasma mirrors

When light interacts with a mirror which is moving towards it at a speed close to the speed of light, its wavelength is shifted into the extreme ultraviolet region of the spectrum. This effect was first predicted by Albert ...

New method for better laser-material interaction

Using ultrashort laser pulses lasting a few picoseconds (trillionths of a second), Lawrence Livermore National Laboratory (LLNL) researchers have discovered an efficient mechanism for laser ablation (material removal) that ...

Gas-detecting laser device gets an upgrade

University of Michigan researchers have refined a gas-sniffing device so that it can detect poisonous gases and explosives in less than half a second.

Nobel-winning physics key to ultra-fast laser research

The technique for generating high-intensity, ultra-short optical pulses developed by the 2018 Nobel Prize for Physics winners, Professor GĂ©rard Mourou and Dr. Donna Strickland, provides the basis for important scientific ...

Ultracold atoms and ultrafast lasers

Two separate research fields have been united in Hamburg for the very first time. Ultrashort laser pulses enable us to observe and manipulate matter on very short time scales, whereas ultracold atoms permit experiments with ...
