Abstract
We propose and demonstrate an all-chalcogenide microwire Raman laser, the first to our knowledge. The gain medium is provided by the Raman effect in a chalcogenide microwire and two Fabry-Perot resonant media are tested for lasing: (1) a cavity made out of a Fresnel reflection at one end of the microwire and a silver coated, broadband mirror at the other end, and (2) a cavity made out of Fresnel reflections at both ends of the microwire. The microwires are pumped in the C-band, and the resulting Raman lasers operate in the L-band. Such an all-chalcogenide microwire laser has the potential to operate over the entire transmission window of chalcogenide glasses, i.e., in the wavelength range of 1.5-10 μm.

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
