“…The authors of [29] proposed to use the fiber with the square core-cladding boundary. Such fiber allowed for transmitting light up to wavelength of 241 nm with optical losses that are comparable with those that were reported in work [30].…”

“…The sizes of the cladding capillaries were comparable with the air core diameter, which should lead to high bend losses. In work [30], silica glass RF with eight capillaries in the cladding was demonstrated. It transmitted light in the spectral region from 350 nm to 200 nm and the loss level was about 1-2 dB/m.…”

“…On the other hand, it leads to excitation of many air core modes due to inhomogeneous construction of the fiber occurring under the drawing. It also leads to a narrowing of the transmission bands [30]. Therefore, it is necessary to carry out the optimization of the RF geometric structure as in the case of light transmission in the mid IR spectral range.…”

Revolver optical fibers (RF) are special type of hollow-core optical fibers with negative curvature of the core-cladding boundary and with cladding that is formed by a one ring layer of capillaries. The physical mechanisms contributing to the waveguiding parameters of RFs are discussed. The optical properties and possible applications of RFs are reviewed. Special attention is paid to the mid-IR hydrogen Raman lasers that are based on RFs and generating in the wavelength region from 2.9 to 4.4 μm.

Annotation. Optical properties of hollow-core revolver fibers are numerically investigated depending on various parameters: the hollow-core diameter, the capillary wall thickness, the values of the minimum gap between the capillaries, the number of capillaries in the cladding and the type of glass (silica and chalcogenide). Preliminary, similar calculations are made for simple models of hollow-core fibers. Based on the obtained results, the optimal design of the revolver fiber for Raman laser frequency conversion (1.56 μm → 4.4 μm in 1 H 2 ) was determined. As a result, efficient ns-pulsed 4.42 µm Raman laser based on 1 H 2 -filled revolver silica fiber is realized. Quantum efficiency as high as 36 % is achieved and output average power as high as 250 mW is demonstrated.
