Second and third harmonic generation in the opaque region of a GaAs wafer is experimentally observed both in transmission and reflection. These harmonic components can propagate through an opaque material as long as the pump is tuned to a region of transparency or semi-transparency, and correspond to the inhomogeneous solutions of Maxwell's equations with nonlinear polarization sources. We show that measurement of the angular and polarization dependence of the observed harmonic components…

Inhibition of linear absorption in opaque materials using phase-locked harmonic generation.

Inhibition of linear absorption for phase and group velocity mismatched second- and third-harmonic generation in strongly absorbing materials, GaAs, in particular, at frequencies above the absorption edge is theoretically predicted and experimentally demonstrated.

Field localization and enhancement of phase-locked second- and third-order harmonic generation in absorbing semiconductor cavities

We predict and experimentally observe the enhancement by three orders of magnitude of phase mismatched second and third harmonic generation in a GaAs cavity at 650 and 433 nm, respectively, well

Second- and third-harmonic generation in metal-based structures

We present a theoretical approach to the study of second- and third-harmonic generation from metallic structures and nanocavities filled with a nonlinear material in the ultrashort pulse regime. We

We study second and third harmonic generation in centrosymmetric semiconductors at visible and UV wavelengths in bulk and cavity environments. Second harmonic generation is due to a combination of

Nonlinear Duffing oscillator model for third harmonic generation

We employ a classical, nonlinear Lorentz–Duffing oscillator model to predict third harmonic conversion efficiencies in the ultrafast regime, from a variety of metal nanostructures, including smooth,

Third harmonic generation at 223 nm in the metallic regime of GaP

New effects in frequency doubling of colliding-pulse, mode-locked dye-amplified pulses and the time profile is affected by depletion and chirp of the fundamental.

Nonlinear Optical Spectroscopy of Gallium Arsenide Interfaces

The physics of buried solid/solid interfaces is interesting for both fundamental and technological reasons. In this thesis, second-order nonlinear optical spectroscopy was used to probe the

Role of phase matching in pulsed second-harmonic generation: Walk-off and phase-locked twin pulses in negative-index media

The present investigation is concerned with the study of pulsed second-harmonic generation under conditions of phase and group velocity mismatch, and generally low conversion efficiencies and pump

Interactions between light waves in a nonlinear dielectric

Abstract : The induced non-linear electric dipole and higher moments in an atomic system, irradiated simultaneously by two or three light waves, are calculated by quantum mechanical perturbation
