Description
THz electromagnetic waves occupy the spectral region between infrared and millimeter waves. Due to the absence of intense, tunable sources of THz radiation, basic research and technology development has been notoriously slow compared to the corresponding advances that have occurred in the uv, visible, infrared, millimeter, microwave, and radio wave regions. The Free Electron Laser (FEL) is an excellent source of intense, tunable, coherent THz radiation. However because of its relatively high cost and large size, very few THz FEL research centers are now in operation. Recently, development of low power coherent THz radiation based on solid state devices has stimulated new interest in THz research and applications.
In this presentation a review is offered of: (a) current development of THz sources, (b) important THz applications in solid state physics, biology, homeland security, medicine, etc., and (c) UH's development program of compact THz FEL sources.
