We are creating a unified UKRI website that brings together the existing research council, Innovate UK and Research England websites.

Ultra

The ULTRA laser facility for advanced time-resolved infrared and Raman spectroscopy is located within the Research Complex at Harwell. It probes the dynamics of molecular reactions (on the femtosecond to microsecond timescales) in solids, liquids and gases and addresses scientific questions in the physical and life sciences.

ULTRA has a range of ultrafast light sources that give unprecedented flexibility to combine 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). This coupled with ultrasensitive spectrometers makes best use of often valuable samples.

The Molecular Structure and Dynamics Group operates both ULTRA and the Optical and Raman Tweezers facilities. The Optical and Raman Tweezers Facility provides the unique ability to manipulate microscopic particles dispersed in a liquid medium and to measure small forces on those particles in a non-intrusive and non-destructive manner.
