摘要
We report fabrication and characterization of hollow photonic-crystal fibers (PCFs) with a diamond-shaped core and a Kagome-lattice cladding. Air-guides modes strongly confined to the hollow care of the fiber are shown to exist within the ranges of wavelengths from 450 to 560 nm and from 470 to 630 nm for two hollow diamond-shaped-core PCFs with slightly different geometry parameters. Polarization-maintaining air-mode guidance of 100-fs second-harmonic pulses of 625-nm Cr:forsterite laser radiation is demonstrated.
