precise and accurate measurements of strong field photoionization and a transferable laser intensity Calibration Standard
Physical Review Letters, 2016Co-Authors: W. C. Wallace, Champak Khurmi, J E Calvert, Klaus Bartschat, M G Pullen, Omair Ghafur, Satya Sainadh U, D E Laban, A N GrumgrzhimailoAbstract:Ionization of atoms and molecules in strong laser fields is a fundamental process in many fields of research, especially in the emerging field of attosecond science. So far, demonstrably accurate data have only been acquired for atomic hydrogen (H), a species that is accessible to few investigators. Here, we present measurements of the ionization yield for argon, krypton, and xenon with percent-level accuracy, calibrated using H, in a laser regime widely used in attosecond science. We derive a transferable Calibration Standard for laser peak intensity, accurate to 1.3%, that is based on a simple reference curve. In addition, our measurements provide a much needed benchmark for testing models of ionization in noble-gas atoms, such as the widely employed single-active electron approximation.

Percent-Level Accuracy in Measuring Strong-Field Photoionization and Laser Intensity
International Conference on Ultrafast Phenomena, 2016Co-Authors: W. C. Wallace, Champak Khurmi, Staya Sainadh, J E Calvert, Robert Sang, M G Pullen, Omair Ghafur, Igor V. Litvinyuk, David Kielpinski, Klaus BartschatAbstract:We present percent-level accurate ionisation yields of atomic hydrogen, argon, krypton, and xenon by few-cycle lasers. From these measurements, a peak laser intensity Calibration Standard is derived, accurate to 1.3% in the 1014 W/cm2 regime.
