Terahertz Radiation by BFi OPTiLAS

THz Emitter -Detector 800nm
Includes all necessary components for assembling of optical system for Time Domain THz Spectroscopy. Usable spectral range extends from 100 GHz to 3 THz. Ekspla introduces the main building blocks for any THz system – THz emitter and detector. THz emitter and/or THz detector consists of a microstrip photoconductive antenna fabricated on low-temperature grown GaAs (LT-GaAs) substrate pumped by ultrafast laser with shorter than 150 fs pulse duration. THz radiation is collected and collimated by integrated Si lens, mounted on X-Y stage. The terahertz (THz) and sub-THz frequency region (100 GHz – 10 THz) of the electromagnetic spectrum bridges the gap between the microwaves and infrared.
