High efficiency solid state laser cooling in Yb<sup>3+</sup>:ZBLANP fiber with tilted fiber Bragg grating structures
Bibliographic record
Abstract
Abstract An optimized fiber structure for use in anti‐Stokes laser cooling of solids is presented. The sample is an optical fiber fabricated from a fluorozirconate glass ZBLANP (ZrF 4 ‐BaF 2 ‐LaF 3 ‐AlF 3 ‐NaF‐PbF 2 ) with a core doped with Yb 3+ ions and optimized to achieve the largest temperature change in the sample starting at room temperature. It is shown that the change in the temperature of the sample is a function of the geometry of the fiber. For each pump power there is an optimized diameter of the fiber core, for which the largest drop occurs in the temperature of the sample. A titled Bragg grating imprinted into the fiber core is suggested to prevent the re‐absorption of anti‐Stokes photons. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
