Advantages of laser engraving is also a principle for the latest applications of laser, that is the use of high-energy laser surface object processing. Shenzhen vertical and horizontal laser engraving mainly high-energy laser beam to the surface of the object to meet high temperature oxidation, so as to change the irradiation area of ??the state, to achieve the purpose of processing. The use of vertical and horizontal laser engraving Shenzhen were marking principle is exposing deep below the surface of the material through a high-energy laser beam is the object, and change the physical and chemical changes, showing traces of engraved or text pattern. Based carried out by the provenance directly modulated master oscillator power amplifier (MOPA) fiber laser zipper head laser engraving machine, than a conventional Q-switched lasers having a wider operating range. This laser has a higher peak power laser engraving machine aluminum housing, and be able to work in a wider range of frequencies. For example, MOPA fiber laser pulse repetition frequency of 25kHz aluminum shell laser engraving machine, when the average output power of 20W, pulse peak power up to 14kW, the operating frequency range up to 1 ~ 500kHz, can also operate in continuous mode. Another important feature of the fiber MOPA laser pulse waveform can be controlled by a preset pulse shape and pulse period, which makes the length of time of the laser pulse, the pulse repetition frequency and peak power can be individually controlled to a large extent. This Q-switched lasers do not have the flexibility and a greater range of parameter adjustment, make MOPA fiber laser has more capabilities to a variety of materials marking. Aluminum shell laser engraving machine, laser engraving machine Chung, fiber laser engraving machine provided by the Dongguan City crown Jun Laser Equipment Co. Dongguan Guan Jun Laser Equipment Co., Ltd. (www.dgaprime.com) strong, credible, in machinery and industrial products, project cooperation and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers.
