Terahertz radiation source mounting arrangements and methods of mounting a terahertz source
First Claim
1. An electromagnetic radiation source mounting arrangement comprising:
- a mounting plate having an aperture positioned to pass a radiation-source-activating pump laser beam, at least one ground contact, and a plurality of energizable contacts;
and a base plate mounted to the mounting plate, the base plate having an aperture positioned to pass the radiation-source-activating pump laser beam and a plurality of electrical contacts adapted to contact the at least one ground contact and at least one of the plurality of energizable contacts on the mounting plate to energize a radiation source mounted to the base plate.

Abstract
Methods and apparatus for detecting variations in electromagnetic fields, in particular, terahertz (THz) electromagnetic fields, are provided. The methods and apparatus employ polarization detection devices and controllers to maintain or vary the polarization of modulated signals as desired. The methods and apparatus are provided to characterize electromagnetic fields by directing the electromagnetic field and a probe beam upon an electro-crystal and detecting the modulation of the resulting probe beam. Detection of the modulation of the probe beam is practiced by detecting and comparing the polarization components of the modulated probe beam. Aspects of the invention may be used to analyze or detect explosives, explosive related compounds, and pharmaceuticals, among other substances. A compact apparatus, modular optical devices for use with the apparatus, sample holders, and radiation source mounts are also disclosed.
