Production of high power femtosecond terahertz radiation
The terahertz (THz) region of the electromagnetic spectrum is attracting interest for a broad range of applications ranging from diagnosing electron beams to biological imaging. Most sources of short pulse THz radiation utilize excitation of biased semiconductors or electro-optic crystals by high peak power lasers. For example, this was done by using an un-doped InAs wafer irradiated by a femto...
متن کاملDiffractive Lenses for High Power Terahertz Radiation Beams
Techniques for manufacturing silicon binary (two level) diffractive lenses and polypropylene kinoform diffractive lenses for the terahertz spectrum range are described. The elements are 1 and 0.8 mm thick, respectively. The silicon lens is manufactured in two versions: with no coating and with a parylene C (polyparaxylylene) antireflection coating. Characteristics of the diffractive optical ele...
متن کاملCompact Power Conditioning and Rf Systems for a High Power Rf Source
High power RF systems have increasing potential for application by the Army. High power RF, or high power microwave (HPM), systems can disrupt or disable enemy communications and weapons systems. Fundamental constraints on the availability of HPM sources to the war fighter are the size and portability. Traditional pulsed power systems capable of producing high power RF signals are massive and s...

متن کاملQuantum Well Intersubband Transitions as a Source of Terahertz Radiation
| It is shown that unipolar quantum well systems have potential as sources of terahertz radiation. It is demonstrated that the electronic interactions within these systems must be manipulated in order to favour radiative emission rather than non-radiative loss. Designs are advanced for tunable emitters and optically excited terahertz lasers.
