Abstract

fetched live from OpenAlex

A simple optical configuration has been proposed to fabricate surface-relief gratings which are key elements in integrated optical devices. This configuration is simple and easy to align thus enabling precise fabrication of a grating which is near to the wavelength used for machining. The system comparatively requires less alignment in order to get the maximum power transmission efficiency. In this paper we are interfering nanosecond pulses from Nd: VYO4 laser system in the infrared regime. The pulses were made to interfere at the focal plane on a stainless steel sample target to fabricate surface relief gratings. Surface characteristics of the gratings have been studied by scanning electron microscopy and optical microscope. The change in the grating period by a simple modification in setup has been shown in this work. Feasibility of the new configuration with respect to alignments and machining efficiency has been verified by our experimental results.

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.
