Demonstration of long-lived high power optical waveguides in air
N. Jhajj, E. W. Rosenthal, R. Birnbaum +2
We demonstrate that femtosecond filaments can set up an extended and robust thermal waveguide structure in air with a lifetime of several milliseconds, making possible the very lon…
Optical beam dynamics in a gas repetitively heated by femtosecond filaments
N. Jhajj, Y. -H. Cheng, J. K. Wahlstrand +1
We investigate beam pointing dynamics in filamentation in gases driven by high repetition rate femtosecond laser pulses. Upon suddenly exposing a gas to a kilohertz train of filame…
Effect of two-beam coupling in strong-field optical pump-probe experiments
J. K. Wahlstrand, J. H. Odhner, E. T. McCole +4
Nonlinear optics experiments measuring phase shifts induced in a weak probe pulse by a strong pump pulse must account for coherent effects that only occur when the pump and probe p…
