Artemis and ULTRA produce femtosecond laser pulses at wavelengths from the infrared to the extreme ultraviolet to build up movies of molecular rearrangement in liquids, gases and solids.

The CLF’s ultrafast laser facilities, Artemis and Ultra, use ultrashort laser pulses to study dynamics on extremely short timescales using a variety of spectroscopic techniques. each facility develops laser techniques and work with academic and industrial users to apply them to understand the fastest motions in matter, across the physical and biological sciences.

The ultrashort laser pulses produced on Artemis are used to strobe the motion of electrons and ions during chemical reactions and phase changes, and build up movies of molecular rearrangement in solids and gas-phase molecules.  Artemis produces femtosecond laser pulses at tuneable wavelengths from the infrared to the extreme ultraviolet.

Ultra combines laser, detector and sample manipulation technology to probe molecular dynamics (on the femtosecond to millisecond timescales) to facilitate innovative research in the physical and life sciences in academia and industry.  Ultra is capable of providing multiple beams, multiple colours (UV – mid-IR), mixed timing patterns (fs-ms) and pulse length (fs-ns and CW).


Each facility provides flexible, synchronised ultrafast light sources. They are both located in the Research Complex at Harwell, and share a new high-repetition rate tuneable IR laser system, as well as having their own laser systems.
