About this event
This event will be held 13:00 - 14:00, in PH30
THz (or sub-mm) radiation lies on the EM spectrum between the IR and microwave regions. It has promising applications ranging from biomedicine and chemistry to defence and security. However a lack of easily available high power sources (>1mW) and convenient detection methods mean there is far less technological exploitation of radiation in this region (the so-called THz Gap) .
Alkali Rydberg atoms, having high sensitivity to EM radiation and atomic transitions spanning the THz gap, make promising THz detectors.
Recent work in Durham  showed that Rydberg atoms could be used to image a single frequency THz field in real time, and relate the field strength directly to SI units. This method is now of
considerable interest in academia and industry as a possible new quantum technology . This talk will outline the way in which Rydberg atoms can function as THz detectors and describe recent extensions to the previous work.
