Manhole aluminum laser engraving machine

 Fiber laser marking machine is the core component master oscillator power amplifier (MOPA), Q modulation and high repetition frequency pulse ytterbium-doped fiber laser, high reliability DC power under the control of dedicated control card driver multimode semiconductor lasers, multimode 970 ± 10nm semiconductor laser emits laser light is coupled to the metal sheath plus 5mm transmission fiber manipulation produces double-clad ytterbium-doped fiber laser in 1.06 micron wavelength, the laser during transmission constantly being magnified beam expander output. Expanded beam after the laser beam is projected onto a galvanometer scanner, and the rapid rotation of the switch through a computer controlled laser galvanometer, so that the laser beam in the X, Y direction scanning by the F-θ lens forms the spot effect aggregation of several micrometers in diameter the workpiece so that the surface moment ablation, vaporization, and finally the formation of a variety of graphic symbols needed in the workpiece surface. Features good quality of light, close to the diffraction limit, TEM00 fundamental transverse mode output, M2 close to 1, the speed of light divergence angle <0.3mrad. Electro-optical conversion efficiency, high repetition frequency, output power stability, single-pulse energy fluctuations of less than 1%, which can achieve high-speed precision laser marking. Environmental adaptability, continuous work under vibration, shock, dust, humidity and other environmental, easy to implement and fiber coupling, can achieve long-distance work. Overall integration, air-cooled, small size, high low-power, high efficiency, reliability, and long life. No optical pollution, no power coupling loss, long maintenance-free, cost-saving, easy to operate using a supported operating system: WIN98 / 2000 / XP. Application materials and application industry Application materials: silicon wafer, circuit chips ,, translucent keys alloy steel, copper, metal plating, ABS, PVC, PES, organic polymers. Applicable industry: Used in depth, smoothness, fine high precision requirements of various fields. Such as precision electronic electrical, instrumentation, hardware, glasses, clocks, IT industry, mold, solar electric volt products. Fiber laser fiber laser marking machine fiber laser applications in recent years become a popular laser physics research, it was agreed that it is possible to fully replace solid-state lasers generation of products. Fiber laser marking machine is the use of a laser beam at the surface of a variety of materials marked with a permanent marker. Marking effect evaporation surface material is exposed by the deep substance, or by chemical and physical changes in the surface energy leads to material and "carved out" signs, or by light burned some substance, showing etching required patterns, text, bar codes and other graphic-called fiber laser marking machine marking machine which refers to the use of a fiber laser, fiber laser has a small (non-water cooled, use air-cooled), just good quality (fundamental mode ), maintenance-free characteristics of fiber lasers are divided into two categories of products: continuous fiber lasers and pulsed fiber lasers.
