This three-year Project Grant from the National Science Foundation (NSF), totaling $300,000, will support theoretical research to develop short-pulsed ultraviolet laser sources. Funded through NSF's Mathematical and Physical Sciences program (CFDA 47.049), the award will promote progress in the generation and characterization of ultraviolet laser pulses.
Specifically, the awardee will conduct numerical simulations of high harmonic generation in a gas jet experiment to analyze the impact of spatial phase dependence across the laser focus. Conditions for coherent buildup of harmonic radiation will be identified and the effects of experimental limitations explored. Additionally, a multi-Gaussian auto- and cross-correlation approach will be investigated and applied to various pulse forms. This theoretical work aims to provide support for developing short-pulsed ultraviolet laser sources, with the goal of advancing science in this important but underdeveloped area of the electromagnetic spectrum.
