Observation of Coherent Surface Optical Phonon Oscillations by Time-Resolved Surface Second-Harmonic Generation
We demonstrate a new time-domain surface phonon spectroscopy. We excite coherent surface optical phonons with an ultrashort laser pulse and probe the free-induction decay with time-resolved surface second-harmonic generation. For both clean GaAs (110) and (100) surfaces, the signals are remarkably large due to the highly localized electron-phonon interaction at the surface and the intrinsic sur...
متن کاملSurface plasmon amplification by stimulated emission of radiation: quantum generation of coherent surface plasmons in nanosystems.
We make a step towards quantum nanoplasmonics: surface plasmon fields of a nanosystem are quantized and their stimulated emission is considered. We introduce a quantum generator for surface plasmon quanta and consider the phenomenon of surface plasmon amplification by stimulated emission of radiation (spaser). Spaser generates temporally coherent high-intensity fields of selected surface plasmo...
متن کاملSymmetry superposition studied by surface second-harmonic generation.
The components of a third-rank g' ' tensor have been split into contributions due to 1-fold, 2fold, 3-fold, and (x}-fold or isotropic rotation axes for a surface of C, symmetry. Theoretical analysis of the rotation patterns obtained by the surface second-harmonic (SH) generation indicates that a complete symmetry analysis cannot be performed without knowledge of the relevant distribution functi...
متن کاملCoherent control and dark pulses in second harmonic generation
We present the results of our study of the second harmonic generation (SHG) in a nonlinear crystal using phase modulated femtosecond laser pulses. We show experimentally that the SHG process is an analogue of two photon absorption (TPA), yet it provides a better way to study coherent control because it enables one easier control of some important parameters. We demonstrate that for a thick nonl...
متن کاملPerfect coupling of light to surface plasmons by coherent absorption.
We show theoretically that coherent light can be completely absorbed and transferred to surface plasmons in a two- or three-dimensional metallic nanostructure by exciting it with the time-reversed mode of the corresponding surface plasmon laser ("spaser"). The narrow-band perfect absorption is a generalization and application of the concept of critical coupling to a nanocavity with surface plas...
