Laser marking of metals and plastics is one of the most widespread of all laser materials processing techniques used throughout the industrial sectors. One remaining challenge is the creation of scanner readable marks on highly reflective materials such as aluminium without the aid of a surface coating. In previous work the authors have presented a novel technique employing a high average power...

Laser-based methodologies for synthesis, reduction, modification and assembly of graphene-based materials are highly demanded energy-related electrodes devices portable electronics. Laser technologies graphene synthesis exhibit several advantages when compared to alternative methods. They fast, low-cost energy saving, allowing selective heating programmable processing, with controlled manipulat...

The study of amino acid based nonlinear optical (NLO) materials with optimum physical properties is an important area due to their practical applications such as optical communication, optical computing, optical information processing, optical disk data storage, laser fusion reactions, laser remote sensing, colour display, medical diagnostics, etc. Also, microelectronic industries require cryst...

Purpose: Purpose of this paper is attempt explanation how laser beam processing influence on the cavitation performance of the Fe-Cr-Mn and Fe-Cr-Co alloys. This kind of alloys are frequently used in Polish power plants to routine repairs of damaged blades working under cavitation loading. Design/methodology/approach: Padding welds of investigated alloys were tested for three cases: after laser...

Laser materials processing normally induces a certain residual stress distribution in the target material. Distributions favoring microcrack propagation lead to reduced fatigue life of the material. This paper investigates the feasibility of altering the stress field by using underwater shock waves in the micron scale. Shock pressure was computed and the stress analysis was conducted, in which ...

Laser-based processing enables a wide variety of device configurations comprising thin films and nanostructures on sensitive, flexible substrates that are not possible with more traditional thermal annealing schemes. In near-field optical probing, only small regions of a sample are illuminated by the laser beam at any given time. Here we report a new technique that couples the optical near-fiel...
