One of the most perspective methods of additive manufacturing is selective laser melting. It
allows producing the parts directly from 3D-model to 3D-object from metallic powders and …

This study concentrates on describing effects of laser heat treatment of Monel 400 and laser
alloying its surface with boron. Surfaces without and with initial boron layers of two different …

Microabrasion-corrosion tests were carried out to investigate how small changes in dilution
affect abrasion-corrosion resistance of Ni–Cr PTA welded deposits onto carbon steel. For …

In this paper, a laser beam from a fiber coupled diode laser source is converted from a
Gaussian-like distribution to a flat-top distribution using a set of homogenization optical …

A novel beam homogenisation system based on a micro-lens array and beam expansion
structure is proposed to convert a Gaussian-distributed circular beam to a flat-top-distributed …

In this paper, aiming to solve the problem of cracks in the laser cladding for stainless-steel
ball valves, a novel method for defect-free processing is introduced. To realize this method …

We proposed and demonstrated a highly efficient sub-microscale focusing from a GaN
green laser diode (LD) integrated with double-sided asymmetric metasurfaces. The …

With the rapid development of laser technology, laser as the light source of night vision
illuminating can realize long-distance and clear imaging, which has been widely used in …

This paper presents the design and fabrication of a novel double-sided aspherical Fresnel
(DSAF) lens on a curved substrate to tackle the Fresnel lens problems such as long focal …
