    Laser cutting is both more precise and less energy-consuming than plasma cutting, but has an upper threshold on the thickness of the material being cut. Xometry's Manufacturing Partner Network offers both Fiber and CO2 lasers that can cut a number of materials including mild steel, stainless steel, aluminum, copper, brass, and exotic alloys. Laser processing of materials is inscribed in that context. As soon as powerful coherent light sources were made available, it was realized that such intense sources of energy could be used to "heat, melt and crystallize" materials, i.e., to promote phase transitions in atomic systems.

    Second-harmonic generation (SHG, also called frequency doubling) is a nonlinear optical process in which two photons with the same frequency interact with a nonlinear material, are "combined", and generate a new photon with twice the energy of the initial photons (equivalently, twice the frequency and half the wavelength), that conserves the coherence of the excitation. However, most of our attention will be devoted to the common rod shape for lamp pumped solid state lasers and "microchips" for diode pumped solid state lasers.

The applications of the laser in material processing are based mainly on the local conversion of the radiation energy into heat [). At high intensities the heat is supplied to the workpiece so fast that losses due to heat conduction during welding and cutting are negligible.

At the same time, the applications of lasers in other industrial areas have also increased substantially. Increased processing speed, low operating cost, and greater capabilities make laser ablation a viable alternative to traditional mechanical machining technology.

This study analysed the impact of a number of operating parameters on graphite. Understanding the physical processes that occur in laser material processing is necessary for developing computational models that simulate the laser/material interaction, and for real-time process monitoring and control.

This work was performed to gain an increased understanding of the dynamics of the vapor ejected from a metal surface during the laser welding by: 2.

There are several advantages of using laser over the conventional processes in cutting, engraving, embossing, denim fading and other applications. In addition, product damage potential is reduced, no/less consumables are needed and no problem of toxic by-product disposal as Cited by: However, laser cutting has an upper limit on the thickness of the material it can cut.
