Ultrafast optics provides a promising avenue for new frontiers of physics on timescales beyond the imagination. As the eld progresses, continuous development of new methods is required to provide an ultimate level of control and understanding of the physical processes behind it. These are largely focused around the synthesis and measurement of intense pulses of light on the femtosecond timescale to generate reliable and coherent radiation in the extreme ultraviolet (XUV) or soft X-ray regions, for use in probing electron dynamics. This has shown promise in such areas as the development of ultrafast electronic devices or new quantum control techniques. This report describes the foundational work carried out in Huxley 007 at Imperial College London - the Attolab - to develop and construct an in-house versatile 3-channel synthesizer and the diagnostic tools needed to accurately measure these electric elds. The main focus of this project has to becomefamiliarized with the extensive range of techniques and technologies within the lab and to overcome experimental challenges faced in this development, as it progresses into the PhD. In addition, analysis work is presented which provides the basis for an experimental collaboration to be carried out atARTEMIS at the Rutherford Appleton Laboratory.
