Scientists have always been interested in the various motions, dynamics and reactions of the world around them. The understanding of chemical reactions, which often proceed through many intermediate states, has been of particular interest. An essential step toward a better understanding of chemical reactions is the study of electronic, atomic and molecular dynamics.

520 $a Scientists have always been interested in the various motions, dynamics and reactions of the world around them. The understanding of chemical reactions, which often proceed through many intermediate states, has been of particular interest. An essential step toward a better understanding of chemical reactions is the study of electronic, atomic and molecular dynamics.
520 $a This work demonstrates a novel spectroscopic method with femtosecond resolution, giving it the capability to directly observe molecular dissociation dynamics. This is made possible by combining a number of recently developed source and detector technologies. EUV light is created by upconverting ultrashort, high intensity, infrared laser pulses through the mechanism of high-harmonic generation. It is then used to initiate dynamics in molecules through valence ionization, inner-valence ionization and shake-up processes. The dynamics are then probed by time-delayed infrared pulses. An ion and electron coincident momentum imaging detector is used to study the dynamics.
520 $a This combination of high-harmonic generation and momentum imaging technologies has permitted us to observe, for the first time, the dissociation dynamics of shake-up states of nitrogen (N2) molecules. Additional molecules (D2, O2 and CO) have also been studied and preliminary analysis points to very interesting dynamics occurring in each case.
520 $a This work also presents the first demonstration of a carrier-envelope phase stabilized, chirped pulse amplifier system using diffraction gratings in the stretcher and compressor, a potentially useful tool for molecular reaction imaging. The amplifier system is cryogenically cooled and exhibits intrinsic long term phase stability. The results represent a significant improvement over previously demonstrated phase coherence for grating-based, femtosecond laser amplifier system.
