Self-focusing and self-compression of intense pulses via ionization-induced spatiotemporal reshaping
Xiaohui Gao, Bonggu Shim
Ionization is a fundamental process in intense laser-matter interactions, and is known to cause plasma defocusing and intensity clamping. Here, we investigate theoretically the pro…

Intrapulse Impact Processes in Dense-Gas Femtosecond Laser Filamentation
Dmitri A. Romanov, Xiaohui Gao, Alexander L. Gaeta +1
The processes of energy gain and redistribution in a dense gas subject to an intense ultrashort laser pulse are investigated theoretically for the case of high-pressure argon. The…

Loss of Polarization in Collapsing Beams
Gauri Patwardhan, Xiaohui Gao, Amir Sagiv +5
We show theoretically and demonstrate experimentally that collapsing elliptically-polarized laser beams experience a nonlinear ellipse rotation that is highly sensitive to small fl…
