Ytterbium-doped fiber laser pumping of a thulium-doped ZBLAN blue fiber laser
Bibliographic record
Abstract
The thulium-doped ZBLAN fiber laser converts infrared radiation in the range 1100-1160 nm to visible radiation around 480 nm through an upconversion pumping process. A brief description of the laser through a rate equation analysis modeling is presented. A compact experimental setup using a diode-pumped Yb<sup>3+</sup> fiber laser at 1108 nm is presented. Single transverse mode blue emission at 482 nm with a maximal output power of 96 mW was obtained. A slight increase of the laser threshold due to photoinduced losses from 103 mW to 240 mW was observed, which is significantly less than previously reported values. Further optimization of the laser efficiency is proposed using Raman fiber laser pumping at 1125 and 1160 nm. Numerical simulations are used to calculate the expected increase in blue output power.

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; a candidate call from one teacher head, not a consensus.
