Hollow-core fiber gas lasers [Invited].
Review in Light, science & applications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Recent years have witnessed significant advancements in hollow-core fiber gas lasers (HCFGLs), driven by developments in hollow-core fiber (HCF) design and fabrication. These novel lasers are characterized by hollow-core structure, providing an ultralong and tiny interaction region for light and gases, thereby enabling light amplification with high efficiency, high beam quality, and tunability. HCFGLs has achieved broadband emission spanning from ultraviolet to mid-infrared (MIR) region, with a record output wavelength exceeding 4.8 μm in silica-based fiber lasers. Output power has surpassed 100 W in the near-infrared and reached an impressive 21.8 W in the MIR region. With the continuing reduction of attenuation in HCFs, particularly in the MIR regime, HCFGLs holds promises for potential applications in trace gas detection, space communication, polymer processing, medical treatment, national defense, etc. In this review, we focus on the basic principles and research progress of HCFGLs. The paradigm shifts history of HCFs are reviewed first. The development history and representative works of HCFGL based on the population inversion and stimulated Raman scattering are then introduced in detail. Finally, the future trends toward power enhancement, spectral expansion, and practical applications are also outlined. We hope this review will provide valuable insights for HCFGL researchers and interested readers, while also offering potential pathways to achieve otherwise challenging laser wavelength outputs and further power scaling.
