Description
Electro-optical detection provides a powerful method for characterizing the electric fields of relativistic electron beams and their emitted radiation. We report on the use of novel thin-film lithium niobate electro-optical sensors for the detection of freely propagating terahertz (THz) pulses and, for the first time, measurements of coherent synchrotron radiation (CSR) at the Karlsruhe Research Accelerator (KARA). The thin-film lithium niobate sensors, implemented as integrated Mach–Zehnder interferometers, combine a strong electro-optical response with engineered velocity matching and a compact device geometry, enabling sensitive detection of transient THz fields. Using these Mach–Zehnder interferometer waveguide structures, we demonstrate efficient coupling of CSR to the sensors and present first measurement results.
