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.

“…The maximum pulse energy is up to 17.6 µJ, corresponding to a 74% quantum efficiency excluding the absorption losses from the bulk optics in the experimental setup (see Supplementary Note 4). Both the pulse energy and quantum efficiency are the highest reported in gas-filled fiber lasers beyond 3 µm wavelength 35,37,39,[43][44][45] . Furthermore, the H 2 pressure of 20 bar required to achieve the highest pulse energy is significantly less than other reported results 37,43 , since in this work the transient Raman regime is efficiently suppressed by using long duration (6.9 ns) pump pulses.…”

Development of novel mid-infrared (MIR) lasers could ultimately boost emerging detection technologies towards innovative spectroscopic and imaging solutions. Photoacoustic (PA) modality has been heralded for years as one of the most powerful detection tools enabling high signal-to-noise ratio analysis. Here, we demonstrate a novel, compact and sensitive MIR-PA system for carbon dioxide (CO2) monitoring at its strongest absorption band by combining a gas-filled fiber laser and PA technology. Specifically, the PA signals were excited by a custom-made hydrogen (H2) based MIR Raman fiber laser source with a pulse energy of ⁓ 18 μJ, quantum efficiency of ⁓ 80% and peak power of ⁓ 3.9 kW. A CO2 detection limit of 605 ppbv was attained from the Allan deviation. This work constitutes an alternative method for advanced high-sensitivity gas detection.

“…Применение кварцевых СПС револьверного типа позволило недавно реализовать лазеры среднего ИК диапазона на основе вынужденного комбинационного (рамановского) рассеяния (ВКР) в молекулярном водороде [2][3][4]. Используя в качестве источника накачки наносекундный эрбиевый волоконный лазер (λ = 1,56 мкм), была достигнута ВКР-генерация на длине волны 4,4 мкм со средней мощностью 250 мВт и квантовой эффективностью 36 % [4].…”
