A Fully Three-Dimensional Kinetic Particle-In-Cell Framework for Modeling Laser-Dielectric Interactions: Few-Cycle Pulse Damage
Joseph R. Smith, Ziyao Su, Simin Zhang +3
We present a fully three-dimensional kinetic framework for modeling intense short pulse lasers interacting with dielectric materials. Our work modifies the open-source Particle-In-…
Femtosecond Self-Reconfiguration of Laser-Induced Plasma Patterns in Dielectrics
Jean-Luc Déziel, Louis J. Dubé, Sandra H. Messaddeq +2
Laser-induced modification of transparent solids by intense femtosecond laser pulses allows fast integration of nanophotonic and nanofluidic devices with controlled optical propert…
Explicit formulation of second and third order optical nonlinearity in the FDTD framework
Charles Varin, Rhys Emms, Graeme Bart +2
The finite-difference time-domain (FDTD) method is a flexible and powerful technique for rigorously solving Maxwell's equations. However, three-dimensional optical nonlinearity in…
MeV femtosecond electron pulses from direct-field acceleration in low density atomic gases
Charles Varin, Vincent Marceau, Pascal Hogan-Lamarre +3
Using three-dimensional particle-in-cell simulations, we show that few-MeV electrons can be produced by focusing tightly few-cycle radially-polarized laser pulses in a low-density…
Saturable Lorentz model for fully explicit three-dimensional modeling of nonlinear optics
Charles Varin, Graeme Bart, Rhys Emms +1
Inclusion of the instantaneous Kerr nonlinearity in the FDTD framework leads to implicit equations that have to be solved iteratively. In principle, explicit integration can be ach…
On the validity of the paraxial approximation for electron acceleration with radially polarized laser beams
Vincent Marceau, Charles Varin, Michel Piché
In the study of laser-driven electron acceleration, it has become customary to work within the framework of paraxial wave optics. Using an exact solution to the Helmholtz equation…
