Abstract
Photoionization and high-order harmonic generation (HHG) in molecular systems under the action of combined infrared femtosecond (fsec) and ultraviolet attosecond (asec) laser pulses are investigated numerically for a one-dimensional non-Born-Oppenheimer ${\mathrm{H}}_{2}^{+}$ ion. It is shown that punctual ``turn-on'' of an asec pulse can trigger the ionization process, which in turn leads to significant enhancement of HHG. The conversion efficiency of HHG can exceed the one obtained from a single fsec pulse by several orders and can be as high as ${10}^{\ensuremath{-}2}$ by controlling the recolliding electron responsible for the maximum order in HHG. The HHG spectrum becomes broader and quasicontinuous near the cutoff. This spectrum can be used to synthesize new single x-ray ultraviolet pulses as short as 250 asec.

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
