Complete Characterization of Ultrafast X-Ray Pulses

We are improving critical technologies needed for the development of laser-driven, table-top ultrafast x-ray sources suitable for ultrafast characterization of transient structures of energized molecules undergoing dissociation, isomerization, or intramolecular energy redistribution. In this SBIR project, Mesa Photonics will develop an X-ray ultrafast laser pulse measurement instrument for complete characterization of femtosecond to picosecond X-ray sources. This technology is critical for the development, control, and efficiency of table-top ultrafast x-ray sources as well as free electron-based sources. In Phase I, we demonstrated our technology for ultrafast X-ray pulse measurement by showing that it will be capable of measuring ultrafast X-ray pulses as short as 20 fs. We also developed new analysis methods that we were able to productize. The Phase II effort will continue with the development of our ultrafast X-ray pulse measurement technology. We will demonstrate the pulse measurement capability on different energy X-ray pulses and different time durations, and develop a single-shot, high speed version for real-time monitoring. Commercial Applications and Other Benefits: Low cost, efficient, coherent x-ray sources will improve medical imaging and diagnosis. Improved imaging for Homeland Security will result in safer ports and airports. These systems can also be used for non-destructive testing, microanalysis, and microscopy.
