Abstract
We report on the first Raman laser based on a fluoride glass optical fiber. The Raman fiber laser was pumped by a 9.6 WTm3+:silica CW fiber laser operating at a wavelength of 1940 nm. A maximum output power of 580 mW was measured at 2185.1 nm, corresponding to a frequency shift of 579 cm(-1) (17.37 THz). We observed a threshold power of 3.8 W and a low power slope efficiency of 29% with respect to the launched pump power. Using those results and the known fiber parameters, we estimated a Raman gain peak value of 3.52*10(-14) m/W, which is lower than the previously reported values.

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
