Enhanced Interband Optical Nonlinearities from Coupled Quantum Wells
Rithvik Ramesh, Madeline Brown, Amberly Ricks +21
The recent, rapid advances in nonlinear chipscale nanophotonics in the visible and near-infrared have been largely driven by manipulating the local dielectric environment proximate…
Observation of Fundamental Limit of Light Localization
Farbod Shafiei, Massoud R. Masir, Tommaso Orzali +4
In disordered media light can be localized in the spaces between scattering sites which average to an optical mean free path (MFP). However the fundamental question of the smallest…
High-charge 10 GeV electron acceleration in a 10 cm nanoparticle-assisted hybrid wakefield accelerator
Constantin Aniculaesei, Thanh Ha, Samuel Yoffe +23
In an electron wakefield accelerator, an intense laser pulse or charged particle beam excites plasma waves. Under proper conditions, electrons from the background plasma are trappe…
Nonlinear Inverse Compton Scattering from a Laser Wakefield Accelerator and Plasma Mirror
A. Hannasch, M. LaBerge, R. Zgadzaj +7
We generate inverse Compton scattered X-rays in both linear and nonlinear regimes with a 250 MeV laser wakefield electron accelerator and plasma mirror by retro-reflecting the unus…
Effects of Laser Polarization and Color on Hybrid Laser Wakefield and Direct Acceleration
Xi Zhang, V. Khudik, A. C. Bernstein +2
We demonstrate that hybrid laser wakefield and direct acceleration (LWDA) can be significantly improved by using two laser pulses with different polarizations or frequencies. The i…
DC-electric-field-induced and low-frequency electromodulation second-harmonic generation spectroscopy of Si(001)-SiO interfaces
O. A. Aktsipetrov, A. A. Fedyanin, A. V. Melnikov +8
The mechanism of DC-Electric-Field-Induced Second-Harmonic (EFISH) generation at weakly nonlinear buried Si(001)-SiO interfaces is studied experimentally in planar Si(001)-SiO$…
