Abstract
A gas-filled hollow-core photonic crystal fiber is used to structure near-infrared ultrashort pulses and enable the generation and time-resolved detection of multi-terahertz radiation. Due to self-phase modulation, near-infrared pulses launched into the fiber experience spectral broadening characterized by the appearance of side lobes at the edges of the spectrum. Phase-locked terahertz generation between 10 and 18 terahertz is achieved by difference-frequency mixing of these spectral side lobes. This method allows for an implementation of time-resolved spectroscopy in the multi-terahertz range through the efficient production of near-infrared pulses with tailored spectra, without requiring ultrabroadband optical sources.

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
