The National Science Foundation (NSF) awarded a $200,000 Project Grant under its Mathematical and Physical Sciences program (CFDA 47.049) to Temple University-Of The Commonwealth System Of Higher Education. The 3-year award, effective August 1, 2023 through July 31, 2026, supports research into transient optical nonlinearities generated by femtosecond laser filamentation in gases. Key objectives include developing predictive models of filament channel formation, tracing the evolution of electronic degrees of freedom in filament wake channels, calculating dynamic polarizability and hyperpolarizability coefficients of ions in filament wake channels, and investigating nonlinear interactions of probe pulses with wake channels. The research aims to advance understanding of intense laser-matter interactions, with applications in areas such as remote atmospheric lasing and attosecond/X-ray pulse generation.
