Abstract

fetched live from OpenAlex

The repetition rate multiplication was observed in a phase-modulated mode-locking fiber laser when the modulation frequency was detuned by a fraction of the fundamental frequency. This phenomenon is quite similar to the rational harmonic mode-locking in amplitude modulated lasers, which almost everybody believed could not exist when applying phase modulation. The harmonics of the amplified driving signal is the reason behind this phenomenon. Because most RF amplifiers cannot avoid generating high-order harmonics of the amplifying signal, the "rational harmonic mode-locking" can be obtained in most phase-modulation fiber lasers when the driving signal is amplified, even in some cases when using linear amplifiers.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
