Wavefront shaping of terahertz radiation using two-color flying-focus pulses with time-dependent focal velocities
A. L. Elliott, H. Markland, K. G. Miller +3
Properly phased two-color laser pulses drive photoionization currents that emit broadband THz radiation. With a conventional two-color pulse, the ionization front travels at a near…
Coupling to multi-mode waveguides with space-time shaped free-space pulses
Spencer W. Jolly, Pascal Kockaert
Guided wave optics, including most prominently fiber optics and integrated photonics, very often considers only one or very few spatial modes of the waveguides. Despite being known…
Control of vortex orientation of ultrashort optical pulses using spatial chirp
Miguel A. Porras, Spencer W. Jolly
Introducing a spatial chirp into a pulse with a longitudinal vortex, such as a standard pulsed Laguerre-Gauss beam, results in a vortex pulse with an arbitrary orientation of the l…
