Brightness enhancement limits in pulsed cladding pumped fiber Raman amplifiers

We analyze theoretically limitations on the brightness enhancement of a multimode pump beam, to be efficiently converted into a diffraction-limited Stokes beam in a cladding-pumped fiber Raman amplifier.

Prediction and verification of the single cladding layer thickness for laser solid forming

MATEC Web of Conferences, 2018
In order to accurately measure the powder effective utilization rate and to predict the single cladding layer thickness in laser solid forming process, a new method to measure powder distribution density is presented in this paper. Using this method, the

PIN‐PMN‐PT Surface Planar Waveguides Realized via He+ Implantation

Nanophotonics, Volume 15, Issue 21, 12 November 2026.
Helium‐ion implantation turns bulk PIN‐PMN‐PT relaxor ferroelectric crystals into high‐quality planar optical waveguides. The guiding surface layer retains its single crystallinity and large electro‐optic response without postimplantation annealing, whereas a buried damage layer acts as the optical barrier.

Cr2O3‐Mediated Phase Transformation and Microstructural Evolution in LDED CuAlMnTi SMA Coatings Toward Resource‐Efficient Wear Protection

EcoMat, Volume 8, Issue 11, November 2026.
The Cr2O3‐reinforced CuAlMnTi shape memory alloy coatings were fabricated via laser direct energy deposition. The addition of Cr2O3 refined the microstructure, altered the phase transformation behavior, and improved the high‐temperature tribological performance.

Synergistic B/Si Microalloying Induced Wear Resistance Improvement in FeCoNiCrCu High‐Entropy Alloy Coatings Prepared by Annular Oscillating Laser Deposition

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT To address the insufficient wear resistance of high‐entropy alloy (HEA) coatings under extreme conditions, FeCoNiCrCu and FeCoNiCrCuB0.03Si0.03 microalloyed coatings were fabricated via annular oscillating laser deposition. This work systematically investigated the effects of synergistic B/Si addition on their phase composition, microstructure,

Learning Adaptive Filtering in the Fourier Domain for Fringe Pattern Analysis: A New Reconstruction Paradigm in Digital Holographic Interferometry

Nanophotonics, Volume 15, Issue 20, 27 October 2026.
The object beam and the reference beam interfere at the camera sensor surface and multi‐angle tomographic recording based on off‐axis digital holography. ABSTRACT Single‐frame fringe pattern analysis in digital holographic interferometry (DHI) is essential for precision phase measurement under dynamic conditions. Recent advances in deep learning within

Laser cladding using scanning optics

, 2012
Laser cladding using scanning optics is a relatively little studied matter. Scanning optics makes the adjustment of laser beam interaction zone numerically possible and it is, therefore, a more flexible optical tool than the conventional static optics. A
