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.
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 liquids, gases and solids.
Ultra combines laser, detector and sample manipulation technology to probe molecular dynamics (on the femtosecond to microsecond timescales) to addr​ess scientific problems in the physical and life sciences. 
Both facilities provide flexible, synchronised ultrafast light sources. Ultra combines multiple beams, multiple colours (UV – mid-IR), mixed timing patterns (fs-µs) and pulse length (20 fs, 50 fs, 120 fs, 2-3 ps, 0.8 ns, 6 ns and CW). Artemis produces femtosecond laser pulses at tuneable wavelengths from the infrared to the extreme ultraviolet.
