Abstract
Gain-switched mid-infrared 1 and 7 mol. % erbium-doped fluoride fiber lasers pumped at 1.7 μm were demonstrated. They delivered 2.8 μm pulsed laser with maximum average powers of 306 mW and 390 mW, respectively, corresponding to recorded laser efficiencies of 43.6% and 35.5%. This work exhibits the potential of the 1.7 μm pulsed pumping scheme for gain-switched 2.8 μm erbium-doped fluoride fiber lasers and this pumping scheme paves the way for high-efficient pulsed fiber lasers in the 3 μm region.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
