描述.Terahertz science and technology is attracting great interest due to its application in a wide array of fields made possible by the development of new and improved terahertz radiation sources and detectors. This book focuses on the development and characterization of one such source - namely the semi-large aperture photoconducting (PC) antenna fabricated on Fe-doped bulk Ga.0.69.In.0.31.As substrate. The high ultrafast carrier mobility, high resistivity, and subpicosecond carrier lifetime along with low bandgap make Ga.0.69.In.0.31.As an excellent candidate for PC antenna based THz emitter that can be photoexcited by compact Yb-based multiwatt laser systems for high power THz emission. The research is aimed at evaluating the impact of physical properties of a semi-large aperture Ga.0.69.In.0.31.As PC antenna upon its THz generation efficiency, and is motivated by the ultimate goal of developing a high-power terahertz radiation source for time-domain terahertz spectroscopy and imaging systems..

Generation of Sub-Picosecond Terahertz Pulses, Fe ion implanted Ga.In.As had a reduced pulse width compared to that obtained from the unimplanted emitters. This reduction in pulse width was attributed to the rapid relaxation of the carriers from the conduction state to the trapped state connected with the Fe ions and vacancies. It was also poss

Ultrafast Spectroscopy,ple by the pump pulse. This assumption is based on the fact that we conduct our experiments at high excitation densities that favor the quick thermalization of hot carriers via carrier-carrier scattering. The cooling of hot carriers occurs via various phonon scattering mechanism among which scatteri

Experimental Techniques, by a Wollaston prism. At this point, the phase modulation of the probe beam is converted to an intensity modulation of the two orthogonal polarizations of the probe beam, which are then steered into a pair of balanced photodiodes. A lock-in amplifier subsequently detects the difference in probe laser light intensities measured by the photodiodes.

Praktisches Lehrbuch der Tuberkulose regime has been of considerable interest to the scientific community of late. The term terahertz is typically used to indicate the region of electromagnetic spectrum between the frequencies 100 GHz (100 × 10. Hz) and 10 THz (10 × 10. Hz) corresponding to the sub-millimeter wavelength range 3 mm to
