The University of Reading has developed a laser laboratory that is capable of showing some of the fastest physical processes known. The Ultrafast Laser Laboratory (ULL) can generate high energy laser light pulses with durations less than one tenth of a millionth of a millionth of a second long. The spectral range available ultimately covers the electromagnetic spectrum from TeraHertz to Vacuum Ultraviolet. The pulses can be tailored to have a particular shape and their properties can be measured.
