Origin of optical second-harmonic generation in spherical gold nanoparticles: Local surface and nonlocal bulk contributions
Origin optical second-harmonic generation spherical gold nanoparticles Local surface nonlocal bulk contributions
2011/8/5
Abstract: The second-harmonic generation of 150 nm spherical gold nanoparticles is investigated both experimentally and theoretically. We demonstrate that the interference effects between dipolar and ...
Singularity-driven Second and Third Harmonic Generation in a ε-near-zero nanolayer
Singularity-driven Harmonic Generation ε-near-zero nanolayer
2011/8/4
Abstract: We show a new path to {\epsilon}~0 materials without resorting to metal-based metamaterial composites. A medium that can be modeled using Lorentz oscillators usually displays {\epsilon}=0 cr...
Tracing the structure of asymmetric molecules from high-order harmonic generation
asymmetric molecules high-order harmonic generation
2014/5/28
We investigate high-order harmonic generation (HHG) from asymmetric molecules exposed to intense laser fields. We show that the emissions of odd and even harmonics depend differently on the orientatio...
Orbital Angular Momentum in Noncollinear Second Harmonic Generation by off-axis vortex beams
Harmonic generation and mixing Optical Vortices Orbital Angular Momentum
2011/8/31
We experimentally study the behavior of orbital angular momentum (OAM) of light in a noncollinear second harmonic generation (SHG) process. The experiment is performed by using a type I BBO crystal un...

Second harmonic Nonlinear frequency phosphide photonic crystal
2011/8/26
We demonstrate enhanced second harmonic generation in a gallium phosphide photonic crystal waveguide with a measured external conversion eciency of 5107/W. Our results are promising for fr...
Harmonic operation of high gain harmonic generation free electron laser
harmonic operation HGHG FEL
2009/8/14
In high gain harmonic generation (HGHG) free electron laser (FEL), with the right choice of parameters of the modulator undulator, the dispersive section and the seed laser, one may make the spatial b...
Effect of a wiggler magnetic field and the ponderomotive force on the second harmonic generation in laser-plasma interactions
Second harmonic generation wiggler magnetic field nonlinear optics phase-matching plasma
2010/4/8
In this paper, we consider second harmonic generation and its phase-matching in an underdense plasma in the presence of a wiggler magnetic field. Wiggler magnetic field plays both a dynamic role in pr...
