Low-loss ultra-large mode area all-solid chalcogenide photonic crystal fiber for 20 W level mid-infrared laser delivery.
To achieve mid-infrared high-power laser delivery, a single-mode large mode area (∼9900 µm2) all-solid photonic crystal fiber (AS-PCF) based on As2Se3 and As2S3 chalcogenide glasses was designed. The finite element method was used to study the influence of structural parameters on the optical properties of the fiber. The AS-PCF was fabricated by the stacking-drawing method after material purification, and the optical loss, the near-field mode distributions, and the high-power laser transmission were measured. The fiber exhibits a minimum loss of 4.62 dB/m, which is the lowest loss among chalcogenide AS-PCF on record, and it can carry at least 20 W of high-power transmission, demonstrating strong potential for mid-infrared laser delivery applications.
