Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Monolithic optical components for splitting of high-power beams

, 2022
Paper 84900QHighly efficient beam splitters are important for a variety of high power laser applications. We prove different approaches like aperture and amplitude splitting for practicability for single- and multimode laser sources.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

One-Dimensional Beam Shaping [PDF]

, 1995
INTRODUCTION Computer-generated holograms have been employed to construct desired transverse and longitudinal twodimensional images. In particular, we have recently solved the problem of shaping the axial intensity distribution of a circularly ...

Optical trapping with superfocused high-M2 laser diode beam [PDF]

, 2015
Many applications of high-power laser diodes demand tight focusing. This is often not possible due to the multimode nature of semiconductor laser radiation possessing beam propagation parameter M2 values in double-digits.

Shaping the far-zone intensity, degree of polarization, angle of polarization, and ellipticity angle using vector Schell-model sources

Results in Physics, 2019
This paper presents a method to control both the shape and polarization of a beam in the far field using a vector Schell-model source. Given a desired far-zone beam shape and polarization, and applying Fourier and statistical optics theory, we derive the
