Subpicosecond, freely propagating electromagnetic pulse generation and detection using GaAs:As epilayers
Using GaAs epilayers with arsenic precipitates (GaAs:As) as the photoconductive material in a broad-band optoelectronic terahertz beam system, we have generated and detected freely propagating, subpicosecond electromagnetic pulses. The receiver signal gave a measured integrated pulse width of 0.71 ps. Fast photoconductive rise times have been achieved which are characteristic of good mobility G...
متن کاملDetection of freely propagating terahertz radiation by use of optical second-harmonic generation.
We report the application of electric-field-induced optical second-harmonic generation as a new technique for measuring the field of freely propagating terahertz radiation. Using silicon as the nonlinear medium, we demonstrate subpicosecond time resolution and a sampling signal that varies linearly with the terahertz electric field. This approach, which is attractive for centrosymmetric media, ...
متن کاملIsir Subpicosecond Pulse Radiolysis System
The highest time resolution of the pulse radiolysis had remained about 30 ps since the late 1960’s. To make clear the primary processes in the radiation chemistry and physics within 30 ps, we developed a stroboscopic pulse radiolysis system for the absorption spectroscopy with the time resolution of 2.0 ps (10-90% rise time). The time resolution of 2.0 ps was estimated from the time-dependent b...
متن کاملPolarization properties of the freely propagating electromagnetic field of arbitrary spatial and temporal form
The angular spectrum of plane waves representation of the freely propagating electromagnetic field in the halfspace z z of a homogeneous, isotropic, locally linear, temporally dispersive medium is employed to describe the polarization properties of the field throughout the half-space z > z in terms of the polarization behavior of either field vector on the plane at z = z. Both the spatial and t...
متن کاملPremixed flames propagating freely in tubes
This paper reports an experimental investigation of premixed propane and methane-air flames propagating freely in tubes 1.5 m long and with diameters 54 and 94 mm. Two regimes of propagation are distinguished by correlating the flame speed and the radius of curvature at the flame tip. The characteristic lengths are then related to the cut-off wavelengths estimated from linear theories and compa...
