Fiber laser is a hot research of physics in recent years, and it is considered as a possible comprehensive substitute for solid state laser. Fiber laser is refers to with rare-earth element doped glass fiber as the gain medium of laser, fiber laser can be in the fiber amplifier based on developed under the action of the pump, fiber easily formed high power density, laser laser energy "particle number inversion" caused by, when appropriate to add a positive feedback loop (a resonant cavity can form a laser oscillation output. Optical fiber laser marking machine is the use of laser beam in a variety of different materials (due to the laser wavelength of the relationship, mainly metal, there are some non metal) surface marked with a permanent mark. Subject effect is expose the deep material through the evaporation of surface material, or by light energy lead to physical changes of surface material and carved a mark, or through the energy of light burned material part, show the required etching patterns, text, bar codes, such as all kinds of graphics.
Low cost, good effect, and can make the fiber laser marking machine miniaturization and intensive;
Fast heat dissipation, low loss, high conversion efficiency, low laser threshold;
Free adjustment, maintenance free, high stability;
The bad working environment, the dust, shock, shock, humidity, temperature has a high degree of tolerance;
Long service life, up to one hundred thousand hours of light time;
Without thermoelectric cooling and water cooling, just a simple air-cooled.
Scope of application:
Hardware tools, medical equipment, plumbing equipment, hard alloy, measuring and cutting tools, machine parts, instrumentation, kitchen utensils, bearings, gears and the valve plate, vehicle fittings, stainless steel products, copper and aluminum products. In addition, fiber laser marking machine can be used for surface of metal and non-metallic marking, such as electronic components, integrated circuits, knives, leather, buttons, hardware equipment, computer and mobile phone keyboard, and so on a series of products to date, bar code, logo and arbitrary patterns.
