Description
The need for THz pulses with 100 µJs of pulse energies at a 100 kHz (or higher) repetition rate that are well synchronized with X-ray free electron laser (XFEL) pulses is paramount to studying novel ultrafast phenomena. Efficient THz generation (3 – 20 THz), coupling, and transport over long distances has posed several challenge. In particular, THz wavelengths makes it impractical to rely on metal waveguide for long distance transport, while free space propagation is prone to strong diffraction. In addition, water absorption causes significant attenuation to THz propagation. We present a tabletop experiment to demonstrate efficient transportation of THz radiation at 3.25 THz using metallic irises. This experiment demonstrates efficient transport of THz radiation over 20 meter distances which notable behavior of slower attenuation compared to free space propagation.
