Photoluminescence mechanism and carrier dynamics for visible-light-emitting porous silicon are investigated with the use of temperature-dependent (77–400 K) and picosecond time-resolved luminescence spectroscopy. The results from porous silicon sam

The transient electroluminescence behavior of a Au/porous silicon/silicon/aluminum structure is investigated by a doubly injected short voltage pulse method. It is found that the electroluminescence response of porous silicon diode is very similar to

The optical second-harmonic-generation technique was used to monitor the chemical reaction of carbon monoxide with oxygen atoms preadsorbed on a polycrystalline silver surface in an ultrahigh-vacuum system. The experiment showed that oxygen atoms ads

Recent experiments on the laser-induced breakdown (LIB) of large transparent liquid droplets are reviewed. A physical model of LIB processes is presented with the aim of integrating the following recent results: (1) the internal and near-field distri

We demonstrate for the first time that a porous silicon layer (PSL), which has a bright light-emission band in the range of 500--700 nm, exhibits a strong visible-range luminescence under the illumination of an infrared ultrashort pulsed laser. The d

The temporally and spatially resolved transmission is measured with a green probe beam through the plasma created by an intense near-IR beam that is incident upon a water droplet. We report the propagation speed of the expanding plasma and the evolut

An optical multichannel detection technique was used to measure simultaneously the time profiles of the input laser pulse and the elastic scattering, as well as the time profiles of the spectrally resolved multiorder stimulated Raman scattering (SRS)

Broadband rotational coherent and anti-Stokes Raman scattering (CARS) and vibrational CARS measurements have been performed to determine the N(2) temperature in a flame (1800-2000 K). Comparisons between these two CARS approaches indicate that, despi

Single-shot spectrally resolved broadband rotational coherent anti-Stokes Raman scattering (CARS) from multiple points along a line intersecting a flow has been observed for N(2) and O(2). A large-angle phase-matching configuration was used to achiev

Optical second-harmonic generation from a ${\mathrm{C}}_{60}$ thin film was used to monitor the orientational phase transition. A jump in second-harmonic intensity was observed around 245 K. This observation is in good agreement with the results obta
