Abstract
We develop a strikingly simple fiber-optics pulse repetition-rate multiplication approach, based on dispersion-induced temporal self-imaging (TSI) effect, in which the rate multiplication factor can be electrically programmed to be any desired integer value. The multiplier setup is composed of an electrooptic phase modulator followed by a dispersive medium. In contrast to the conventional TSI-based rate-multiplication techniques, the required dispersion is fixed in this method and does not depend on the multiplication factor. Programming the output repetition rate will be then assigned to a preprocessing step where the overall phase of the input pulses is modulated by a phase modulator. Herein, we derive in detail a condition for the required dispersion and introduce an analytical equation for the temporal phase modulation. To validate the derived expressions, proof-of-concept experiments have been carried out and we have achieved high-quality tunable rate multiplication, by factors ranging from 1 to 4, of mode-locked fiber lasers with input repetition rates of 10 and 4.85 GHz, respectively.

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 it
