unmatched. By focusing the laser beam, can produce high temperature from thousands to ten thousands degrees
at the focal point, making it possible to process almost materials.
Laser marking is that laser beam to engrave permanent marks on the surface of various materials. Marking effect
is according to evaporation of materials’ surface to expose the deep material; or by the action of light, causes
chemical or physical changes on the surface of material to “engrave" traces, display the needed graphics and
texts.

Chapter 4 Principle of Laser marking
4.1 Principle of Laser marking
When some materials were motivated, its atoms (or molecules) at a high level than in low level, the distribution of
the material and energy level difference of the corresponding frequency is able to make the radiation. English” laser"
is abbreviation of Light amplification by Divulgate of radiation
Laser is constituent by working medium and pump sources in the closed pump cavity. Compared with other light
source, laser has good monochromatic, good coherence, well directivity and high brightness.
1) Good monochromatic: Ordinary light source includes the wide wavelength range, be the line width, such as the
sun will contain all the visible wavelengths, but laser with single wavelength.
2) Good coherence: Laser beam added together, its amplitude is stable, can keep the light waves before and after
the phase relationship constant for quite a long time, this is can not be reached by any other light source.
3) Well directivity: Ordinary light emission of light shooting, big beam divergence; The angle of laser divergence is
small, generally for a few mill micro
4) High brightness: Laser beam through an optical system (such as lens) focused on a small area, has very high
brightness.
4.2 Brief of Laser Producer
The working medium of the laser can be gas, liquid or solid.Most of the working medium of gas laser is composed of
atoms, molecules or a mixture of both.The working medium of solid state laser is composed of atoms or ions doped
in some crystal.And the working medium of liquid laser by dissolved in the liquid in the large molecular weight
molecules.
Under the condition of a specific pump, all of these working medium can achieve the population inversion, and
generate a certain wavelength of laser output.
Using cladding, parallel pump technology, multiple laser diode coupled to the cladding fiber at the same time, can
obtain higher power laser output.Its basic principle is shown in Diagram 4-1.

Laser marking is the use of high energy laser beam irradiation on the surface of work piece, light turned into heat
energy instantaneously, because evaporation on the surface quickly, thus engraved out text and graphics we need,
to be permanent anti-fake signs.
The feature of laser marking is non-contact processing, can be marking on any of the deformed surface engraving,
no distort on work piece and it is suitable to mark on metal, plastic, glass, ceramic, wood, leather and other
materials.
Laser can be marking on almost parts (such as piston, piston ring, valve, valve seat, hardware tools, sanitary ware,
electronic components, etc.), and can stand resistance, easy to realize automation production
TY –G908 Co2 laser marking machine marking by scanning method, the laser beam reflect onto the two lens,
computer controlled scanning motor drive lens to rotate along the X, Y axis, after focusing the laser beam to the
marked on the work piece, thus forming the trace of the laser marks. Its working principle as shown in diagram 4-2.

TY – G908 laser's power is the device to supply power to Co2 laser, the input voltage is AC220V AC. Installed in the
marking machine control box.
5.3 Fiber laser
TY-G908 Co2 laser marking machine adopts pulsed fiber laser, with good laser output and service life is long, which
is installed in the casing of Co2 laser
5.4 the galvanometer scanning system
The galvanometer scanning system is made up of optical scanner and servo control 2 parts.The whole system
adopts new technology, new material, new technology, new working principle, design and manufacturing.
Optical scanner USES the moving magnet deflection works of servo motor. Has a large scanning and peak torque,
The load inertia is great, electromechanical time constant is small, the working speed is fast and it is stable and
reliable. Precision bearing anti-backlash agency provides super axial and radial run out error; "Electronic torsion
bar" replaces the traditional elastic material torsion bar, by doing so greatly improves the working life. Working
principle of the zero power at any position keep both reduced the use of power consumption, and reduce the
heating effect of the device, dispense with constant temperature device; advanced stability of high precise position
detection sensor technology with high linearity and the performance of high resolution, high repeatability, low drift.
An optical scanner can be divided into system scan X direction and Y direction scanning system and each servo
motor shaft fixed on the laser reflective lenses. Each servo motor is made by computer digital signal to control its
trace.
5.5 Focusing system
The role of focusing system is to parallel laser beam focused on the point. Mainly uses the f - theta lens, because
different f – theta has different the focal length, marking effect and scope is different too. TY-G908 Co2 laser
marking machine pause with imported high-performance focusing system. The standard configuration of lens focal
length f is160 mm and effective scanning range Φ is 110 mm. The user can be selected according to need types of

７
lens.
Optional F - theta lens are:
f＝100mm, its effective focusing range is Φ 65 mm.
f＝160mm，its effective focusing range is Φ 110 mm.
5.6 Computer-control system
Computer control system is the laser marking machine control and command center, is also the carrier of software
installation. Through the acousto-optic modulation system, coordinated control the galvanometer scanning system
to mark processing.
T TY-G908 Co2 laser marking machine computer control system mainly includes a full set of Dell case, motherboard,
CPU, hard disk, memory chips, D/A card, floppy disk, monitor, keyboard, mouse, etc.

Chapter7 Maintenance
TY-G908 Co2 laser marking machine is mainly composed of electronics, precision instruments, optical device, the
use of the environment and daily maintenance have higher requirements
7.1 Attention of Maintenance
1) When the machine doesn't work, should turn off marking machine and computer power supply.
2) When the machine is not working, cover the field lens to prevent the dust pollution on the lens.
3) The machine is at work in high pressure state circuit, please don't maintain when it work to avoid electric shock
accidents.
4) This machine with any fault should cut off power supply immediately
5) When the equipment used for a long time, the dust in the air will be adsorbed onto focus lens, at best it will
reduce the power of laser marking effect; at worst cause optical lens endothermic temperature that then burst.
When marking effect is not good, please check carefully if the focus lens' surface is contaminated.
If it is a focus lens surface is contaminated, should take down the focus lens to clean the surface on the bottom.
