Abstract : In studies supported by this research contract, we have investigated both the fundamental aspects and spectroscopic applications of optoelectronic techniques of generation and detection of sub- picosecond electromagnetic pulses. The original research objectives pursued under this contract included the development of significant new capabilities and an improved fundamental understanding of the physical mechanisms involved in the optoelectronic generation and detection of THz radiation. The characteristics of such optically excited THz emitters with respect to the scaling of their peak THz intensities using higher optical fluences and enhancements in their THz frequency response were also to be explored. One of the main issues addressed by these studies was the development of new bright coherent sources and sensitive detectors to enable linear and nonlinear spectroscopy in the far infrared region of the electromagnetic spectrum.
