Abstract

Anti-resonant hollow core fibers (AR-HCF) have been investigated for several use cases relating to high power transmission. Single mode, low-loss operation is needed in high-speed telecommunications and in high-energy beam delivery applications. In these fibers, higher order modes leak out of the core through the surrounding capillaries and subsequently are highly attenuated upon propagation resulting in effective mode filtering. With regards to CW operation, 900W have been delivered through a single resonant ring AR-HCF, and 1kW through a nested AR-HCF. This study presents an experimentally derived performance comparison of the spatial, spectral, and loss metrics between these two types of fibers when using an identical 1kW laser source.
