Summary on Grant Application Form |

The proposed program of research will build upon the work of the past decade in the measurement of extremely fast events by optical time-resolved spectroscopy. In the first thrust we propose to develop a novel method for measuring electric fields with single optical cycle temporal duration, and to measure pulses that are far from transform limited. In this regime it is very difficult to avoid space-time coupling in handling ultrabroadband pulses, and therefore methods for characterizing the field at a single point in the beam will necessarily fail. The plan of approach will be to apply the dimensional economy of detector usage in spectral interferometry to enable sampling of a spatial cross-section of the transverse beam profile of the pulse. In addition, novel methods of locating the relevant parts of the signal away from the baseband noise of the detector will be developed. Applications to the formation of continua in microstructure fibers will be explored . The aim of the second research thrust is to develop methods for the complete characterization of ultra-short pulses in the X-ray region of the electromagnetic spectrum with durations as short as a few attoseconds. The plan of approach will be to make use of the natural ability of X-rays to ionize atoms to generate electronic signals from which the X-ray pulse field may be extracted.There are two fundamental challenges: extending the present techniques for optical pulse characterization into the regime of extremely short mean wavelengths, and extending them to extremely short duration pulses.
