Ultrafast Laser Beam Shaping - Filaments and Light Sheets for Engineering Periodic Diffractive Structure in Bulk and Fibre Glasses
Bibliographic record
Abstract
Ultrafast laser pulses have been molded with a spatial light modulator in three dimensions to control the shape and contrast of refractive index elements and facilitate their assembly into micro-optic diffractive elements in bulk glasses and optical fibre. Both one-dimensional and two-dimensional grating arrays are presented. Laser interactions were varied from gentle modification of refractive index contrast (i.e., <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\Delta \mathrm{n}\sim 0.01$</tex>) to nano-explosions forming open nano-capillaries and nano-planes, enabling the engineering of highly functional and compact microsystems.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
