## Abstract In this article, a hollow core photonic band gap fiber is numerically investigated to obtain lowβloss waveguiding in the terahertz region (0.1β10 THz) of the electromagnetic spectrum. Waveguide design in this spectral region is an arduous challenge due to the highβconductivity losses of
We demonstrate hollow-core photonic-crystal fibers (PCFs) with a core diameter of 45 ΞΌm and a period of the photonic-crystal cladding of 7 ΞΌm. These fibers are shown to allow a waveguide delivery of 4-mJ 15-ns pulses of 1.06-ΞΌm radiation of a __Q__-switched Nd: YAG laser. Hollow PCFs reported in thi
