Dephasingless two-color terahertz generation
Tanner T. Simpson, Jeremy J. Pigeon, Kyle G. Miller +3
A laser pulse composed of a fundamental and an appropriately phased second harmonic can drive a time-dependent current of photoionized electrons that generates broadband THz radiat…
Programmable and arbitrary-trajectory ultrafast flying focus pulses
M. V. Ambat, J. L. Shaw, J. J. Pigeon +4
"Flying focus" techniques produce laser pulses with dynamic focal points that travels distances much greater than a Rayleigh length. The implementation of these techniques in laser…
Spatiotemporal control of two-color terahertz generation
Tanner T. Simpson, Jeremy J. Pigeon, Manfred Virgil Ambat +5
A laser pulse composed of a fundamental and properly phased second harmonic exhibits an asymmetric electric field that can drive a time-dependent current of photoionized electrons.…
Exact solutions for the electromagnetic fields of a flying focus
D. Ramsey, A. Di Piazza, M. Formanek +10
The intensity peak of a "flying focus" travels at a programmable velocity over many Rayleigh ranges while maintaining a near-constant profile. Assessing the extent to which these f…
Spatiotemporal control of laser intensity through cross-phase modulation
Tanner T. Simpson, Dillon Ramsey, Phil Franke +5
Spatiotemporal pulse shaping provides control over the trajectory and range of an intensity peak. While this control can enhance laser-based applications, the optical configuration…
Optical Shock-Enhanced Self-Photon Acceleration
Philip Franke, Dillon Ramsey, Tanner T. Simpson +2
Photon accelerators can spectrally broaden laser pulses with high efficiency in moving electron density gradients. When driven by a conventional laser pulse, the group velocity wal…
Nonlinear spatiotemporal control of laser intensity
Tanner T. Simpson, Dillon Ramsey, Philip Franke +4
Spatiotemporal control over the intensity of a laser pulse has the potential to enable or revolutionize a wide range of laser-based applications that currently suffer from the poor…
