This video shows our 20w MOPA fiber laser marking machine for marking different color on stainless steel. The new design fiber laser engraving machine for color marking is mainly used for marking and engraving black, white, grey, colors on metal surface such as stainless steel, titanium, etc. What are the detailed materials applied for optical fiber laser marking machine ? Many type of metals: Gold,Silver,Stainless Steel,Copper,Aluminum,chrome Brass,etc Alloy and metal oxides: Anodized Aluminum Some non-metallic materials & Special surface treatment:silicon wafer,ceramics,plastic,rubber,epoxy resin,ABS,Printing ink, Plating, Spraying, Coating film.

What is laser marking? "Laser marking" stands for marking or labeling of workpieces and materials with a laser beam. In this regard, different processes are distinguished, such as engraving, removing, staining, annealing and foaming. Depending on the material and the quality requirement, each of these procedures has its own advantages and disadvantages. How does a laser marking machine work ? Laser technology basics All lasers consist of three components: 1.  An external pump source 2.  The active laser medium 3.  The resonator The pump source guides external energy to the laser. The active laser medium is located on the inside of the laser. Depending on the design, the laser medium can consist of a gas mixture ( CO2 laser marking machine ), of a crystal body (YAG laser) or glass fibers ( fiber laser marking machine ). When energy is fed to the laser medium through the pump, it emits energy in the form of radiation. The active laser medium is l...

Currently, in the laser marking machine industry, there are two types of laser marking machine, including fiber laser marking machine and MOPA laser marking machine. Fiber laser marking machine MOPA color laser marking machine Fiber laser marking machine has developed rapidly in recent years, it is widely used in electronic 3C products, machinery, food, packaging and so on. But in order to get a more beautiful mark effect and more efficient production and processing, The new technology: MOPA laser marking machine appears. As a new technology, what is the difference between MOPA laser marking machine and fiber laser marking machine? Does it have any new technology and advantages? 1. Now a lot of electronic products are used alumina material as the product of the shell. Fiber laser marking machine marking on the alumina sheet, it is easily lead to material deformation. And MOPA laser marking machine, which can make the material is not easy to deformation. 2. At pr...
