Abstract

fetched live from OpenAlex

A frequency-stabilized Brillouin random fiber laser (BRFL) realized by a self-inscribed transient population grating (TPG) is proposed and demonstrated for the first time, to the best of our knowledge. The TPG is formed via the redistribution of the population in erbium-doped fibers (EDFs) by bidirectionally injected phonon-controlled random laser beams. Long-lifetime metastable ion states in EDFs basically prolonged the time dynamics of a stimulated Brillouin scattering (SBS) laser up to milliseconds. Consequently, significant random modes are suppressed with low relative intensity noise, owing to reduced mode hopping in a Stokes random laser, hence one dominating lasing mode at milliseconds of lifetime is established from the competition of numerous random modes, which is proved theoretically and experimentally via TPG.

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.
