Fiber laser marking machine for the core part ----- fiber lasers, in front of about fiber laser marking machine works also with talk about the working principle of fiber lasers in fiber lasers has not appeared before in the marking the industry, the most used is CO2 and YAG laser marking machine laser marking machine, CO2 laser which is divided into two kinds, namely RF metal tube laser (mostly imported and domestic performance yet stable), and CO2 laser tube two kinds, while the majority of which provides a laser-made, between the Institute of encouraging domestic institutions and a number of developed, resulting in many of these domestic CO2 glass tube manufacturer, or else their technology from universities or else from the Institute of another YAG laser marking machine can also be divided into two types, namely: krypton lamp pumped YAG laser marking machine and diode-pumped laser marking machine is the former which is now almost a years eliminated, but at the moment people still use the former, and even production, because some special industry can not do without him, the latter since 2006 accounted for an absolute leadership position, but it is estimated will be the earliest in 2013 Fiber laser marking machine eliminated,the laser marking machine price is very good.


Fiber laser marking machine works as follows:


The basic structure of the frame fiber laser marking systems are fiber lasers, he is also the core of laser marking system, and so the laser pump source is 808NM laser diode, which is a multi-mode laser diode, through the semiconductor chip and cooling cooling fans to metals and to this 808NM laser diode pump sources such stable, and long wavelength drift factors, which may affect the laser power does not occur. 808NM laser diode through a plurality of multi-branch coupling to into a single fiber laser material --- which an optical fiber is doped with rare earth elements (Nd, Yb or Er), full mirror, mirror as well as the output fiber grating cavity, can be pulsed and continuous operation can be achieved pulses of up to 100K.


This application up until the 1990s fiber lasers with very many advantages (compared to the semiconductor laser marking machine)


1, single-mode output, both for the TEM00 mode


2, good heat dissipation characteristics, the cooling fan can be


3, high optical conversion efficiency, 808NM pump becomes about 1060 fiber laser light. Pump laser source which is a laser diode 808NM, a low voltage, thus ensuring a high electro-optical efficiency of the fiber laser 30%


4, the overall structure is compact, is particularly suitable for use as a portable marking machine can achieve RF CO2 laser marking machine is the effect. 10W ~ 20W fiber laser volume average power output of finished just 24CM * 25CM * 10cm, and no large water-cooled systems, very good installation marking design space. driving power of this laser light pump size and Nd-YAG laser is negligible compared.


5, in which a laser is between 20-80KHz pulse frequency, repetition rate is so high working speed for high precision laser marking IDM


Fiber laser marking machine component are:


1. fiber laser pumped laser driving power source


2. the laser marking card, also known fiber laser controller is used to control the operating state of the fiber laser, and can control the movement of the galvanometer, a fiber laser is also controlled by a set of power output, the detailed marking software and marking laser card specification can refer les website or call our sales staff.


3. digital galvanometer marking head (some models are using analog galvanometer), galvanometer system is an important component of the fiber laser marking systems, along with digital high-speed motion laser galvanometer, the required marking on the product components Marking card software is set to carve a specific two-dimensional trajectory. Digits and analog galvanometer respectively by the two sets of high-precision angle servo motors and motor driver board, as well as high-fiber wavelength anti-reflection mirror, a control another set of X-axis Y-axis control. Angle servo motor in the fight Under the control of the standard card and the computer, the two rotatable mirror angle, respectively, so that these two laser beams reflected by the reflection mirror, focused by a field lens to a different location on the workpiece. Controlling an optical fiber marking laser beam on the workpiece subject to the set play text or drawings


4. field lens, optical fiber through which the laser beam is focused onto the surface, this is enough energy intensity of the optical accessory control marking format,the prospect of laser marking machine for sale is very good.
