Laser marking and processing have several parameters that are programmable and can affect the results you achieve on a specific material or substrate. un laser au gaz (hélium et néon) puis en 1966, Peter Sorokin construisit le premier laser à colorant. endstream endobj 28 0 obj <> endobj 29 0 obj <> endobj 30 0 obj <>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC/ImageI]/ExtGState<>>> endobj 31 0 obj <> endobj 32 0 obj <> endobj 33 0 obj <> endobj 34 0 obj <> endobj 35 0 obj <> endobj 36 0 obj [/ICCBased 53 0 R] endobj 37 0 obj [/Indexed 36 0 R 255 54 0 R] endobj 38 0 obj <> endobj 39 0 obj <> endobj 40 0 obj <> endobj 41 0 obj <> endobj 42 0 obj <> endobj 43 0 obj <> endobj 44 0 obj <>stream The main laser parameters that can be controlled during processing include the laser power, q, the beam radius, rb, the specimen or work-piece velocity, v, and the beam mode, which may be stationary, spinning, top hat, or Gaussian (Ion, 2005); in addition, in the case of alloying, the composition and concentration of the alloy, and if the processing involves a gas such as … Research parameters optimization of “LASER BEAM MACHINE “as laser beam machine, cutting speed power, gas pressure, laser power. In many applications, these parameters define success or failure and, therefore, their control and optimization seems to be crucial. ���Vv��,�O!LM9�&�:��c�U. Une source Laser peut fonctionner en soudage, en coupage, en marquage et en gravage en changeant seulement le débit et quelquefois le gaz auxiliaire. The most commonly measured laser beam parameters besides power or energy are beam diameter (or radius), spatial intensity distribution (or profile), divergence and the beam quality factor (or beam parameter product).
