Laser Instrumentation for Attosecond Experimentation
Abstract
Isolated attosecond pulses are produced with instrumentation developed in a multi-investigator collaborative MURI effort and used for first experiments in attosecond electron dynamics. A new method of ionization phase match gating is developed for isolated attosecond pulse production, and wavelength tunability of the isolated attosecond pulses is achieved. The isolated attosecond pulses are used for optical streak-field spectroscopy experiments conducted in neon and sulfur hexafluoride with both time of flight electron and mass spectrometry, as well as velocity map imaging (VMI) detection. The results reveal the isolated nature of the attosecond pulses, and by high field streaking the pulse contrast is determined. A system is developed to generate high harmonics from low pulse energy pulses by intracavity buildup. An apparatus to perform solid-state experiments using plasmon enhanced surface fields is in operation. Novel soft x-ray optics are produced by the combination of new materials, and the shortest possible pulses (80 as) are achieved by the use of these optics in a European collaboration.
