Laser cooling of solids under the influence of surface phonon polaritons
Bibliographic record
Abstract
Laser cooling of solids with anti-Stokes fluorescence in rare earth-doped low phonon samples, which support surface phonon polaritons (SPhP), placed in the vicinity of the sample supporting SPhP in the same or different wavelength region is considered in this paper. As an example, the laser cooling process in an ytterbium-doped yttrium aluminum garnet (Yb3+:YAG) sample placed near yttrium aluminum garnet (YAG) as well as silicon carbide (SiC) samples has been investigated. All Yb3+:YAG, YAG, and SiC samples can support SPhPs in different frequency ranges. It was shown that for short distances between samples, when SPhPs propagating in the sample undergoing laser cooling and SPhPs propagating in the next sample supported at room temperature are coupled, the laser cooling process can deteriorate substantially. In the opposite case, the SPhPs do not influence the cooling process significantly, even if the distance between the samples is less than the dominant wavelength of thermal radiation. The influence of coupled SPhPs on the laser cooling process in the case of samples with different sizes and for different distances between samples was investigated. These results are important for the development of optical solid state cryocoolers.

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.
