Watching the ultrafast dance moves of a laser plasma

Great leaps in science and technology have been propelled by recent advances in seeing fast evolving physical phenomena, as they happen. Femtosecond lasers from the infrared to the X-ray region have enabled us to 'watch', ...

New method measures super-fast, free electron laser pulses

New research shows how to measure the super-short bursts of high-frequency light emitted from free electron lasers (FELs). By using the light-induced ionization itself to create a femtosecond optical shutter, the technique ...

Breakthrough for laser-induced breakdown spectroscopy

Laser-induced breakdown spectroscopy (LIBS) is a rapid chemical analysis tool. A powerful laser pulse is focused on a sample to create a microplasma. The elemental or molecular emission spectra from that microplasma can be ...

Gold in limbo between solid and melted states

If you heat a solid material enough, the thermal energy (latent heat) causes the material's molecules begin to break apart, forming a liquid. One of the most familiar examples of this phase transition from a well-ordered ...
