We investigate an iris waveguide designed for installation in the long halls of free-electron laser facilities for THz radiation propagation. We approach this problem theoretically and validate our results using numerical wavefront propagation techniques. An iris line, optimised for 3 THz, can propagate radiation over 300 m with a transmission coefficient (T) of 0.74. Furthermore, a line...

We report on an experimental campaign accompanied by simulations of narrowband multicycle terahertz generation by nonlinear optical conversion of tunable high-energy pump pulse trains. We explore the parameter space of this new approach and demonstrate its potential to boost current sub-percent optical-to-THz conversion efficiencies.
