In particular, by optimizing the process of high-harmonic generation using shaped light pulses, we generate a large data set and analyze its statistical behavior. This behavior is then compared with theoretical predictions, verifying our understanding of the attosecond dynamics of high harmonic generation and uncovering an anomalous region of parameter space. PAPER B, 2000: High-harmonic generation is one of the most extreme nonlinear-optical processes observed to date. By focusing an intense laser pulse into a gas, the light-atom interaction that occurs during the process of ionising the atoms results in the generation of harmonics of the driving laser frequency, that extend up to order ~300 (corresponding to photon energies from 4 to >500eV). Because this technique is simple to implement and generates coherent, laser-like, soft-x-ray beams, it is currently being developed for applications in science and technology including probing of dynamics in chemical and materials systems and for imaging. In this work we demonstrate that by carefully controlling the shape of intense light pulses of 6-8 optical cycles, we can control the interaction of light with an atom as it is being ionised, in a way that improves the efficiency of x-ray generation by an order of magnitude. Furthermore, we demonstrate that it is possible to control the spectral characteristics of the emitted radiation and to "channel" the interaction between different-order nonlinear processes. The result is an increased utility of harmonic generation as a light source, as well as the first demonstration of optical pulse-shaping techniques to control high-order nonlinear processes. (6) a statement stating why the result satisfies that criteria Dr. Bartels uses an evolutionary optimization algorithm to shape laser pulses to distort molecules in specific ways to catalyze chemical reactions, with the ultimate goal of manipulating large molecules, for example proteins and enzymes, in a biological cell. The method has also been used to create new quantum behaviors at the atomic level. The learning component is a relatively simple evolution strategy. Human can probe quantum systems, but are not capable of exploring different quantum behaviors in an fast automated fashion. In a sense, the results are beyond human competitive. There is also no doubt that this is a major scientific result which was achieved using evolutionary computation. The results are completely unexpected and amazing from a physical point of view: behaviors are being evolved that were not known to be physically possible. This includes anti-correlated attosecond harmonics in quantum systems. The ability to move beyond the nanoscale to the attoscale is a major breakthrough, and the potential applications of controlling the behavior of materials at atomic level are enormous. This is also work that is not known in the GEC community. It is also something the GEC community would fine extremely interesting and stimulating. Attached is another short paper from Nature from 2000 that is quick and easy to read and has been highly cited. Quoting from the conclusions of the paper: The results "demonstrate a new type of intra-atomic 'phase matching' between the laser field and the wavefunction of the ionized electron." "From a quantum point of view, our optimized laser pulse can adjust the quantum phase of the electron wavefunction ... to optimize it for a particular harmonic feature." Dr. Bartels has already received the following awards for his work: 2005 Sloan Foundation Award. 2005 Beckman Young Investigator Award. 2005 ONR Young Investigator Award. 2004 Adolph Lomb Medal from the Optics Society of America. 2004 NSF CAREER Award.
