Abstract

fetched live from OpenAlex

We examine the laser possibilities offered by Tm 3+ -doped KY 3 F 10 . After crystal growth and X-ray diffraction analysis, the optical properties of thulium ions in KY 3 F 10 are determined for the first time. Absorption and emission spectra recorded at low temperatures are used to obtain a set of Stark sublevels, whereas the room-temperature absorption spectra have been allowed to fit the three phenomenological Judd-Ofelt (JO) parameters. The emission line strengths, branching ratios, and radiative lifetimes of levels from 3 F 4 up to 1 D 2 are then deduced. A comparison between the calculated lifetimes and the measured luminescence decay curves permits us to check the reliability of the JO analysis for this system. The potential of Tm:KY 3 F 10 for laser emission from 3 H 4 or 3 F 4 emitting levels is briefly examined.PACS Nos.: 42.55.Rz, 78.50.Ec, 78.47.+p, 81.10.Fq.

Full frame distilled prediction

Teacher imitation

Not 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.
