Cavity based THz photoconductive switch: towards high average power
Résumé
Reaching milliwatt average powers and room temperature operation for THz sources has become the key challenge for the uptake of THz applications that require real-time imaging. This criteria remains extremely challenging. By placing a photoconductive switch within a quasi-resonant cavity, we are able to show average power around 2mW which is an important development towards room temperature THz imaging.
