The working principle of laser marking machine

The laser marking is with a laser beam to get permanent marks on a variety of different material surfaces.

The effect of marking is to expose the deep matter by the evaporation of the surface material,

or to “mark” the trace by the chemical and physical reactions of the surface material caused by the laser energy,

or to burn some of the material by laser energy, light to achieve the needed patterns and text.

As mentioned in previous email, There are 7 kinds of laser machines, respectively Lamp pumped YAG laser marking machine, Semiconductor pumped laser marking machine, Fiber laser marking machine, CO2 laser marking machine, Mopa laser marking machine, UV laser marking machine, Green laser marking machine.

After introduction of Lamp pumped YAG laser marking machine, Semiconductor pumped laser marking machine, Fiber laser marking machine,

Now let us explore its working principle of rest 3 models.

CO2 laser marking machine is carbon dioxide laser marking machine. It is the laser galvanometer marking machine which uses CO2 gas as the working medium. CO2 laser uses CO2 gas as the medium. It fills CO2 and other auxiliary gas into the discharge tube and high pressure onto the electrode. the discharge tube glow discharge, Then the gas releases 10.64um wavelength laser. After laser energy amplifies, through scanning of the vibration Mirror  and focusing of F-Theta mirror, controlled by the computer and laser marking control card, it can mark images, text, numbers, lines of the mark on the workpieces according to the user’s request

UV laser marking machine belongs to laser marking machine series. but its wavelength is 355nm.
The machine uses the third-order cavity frequency doubling technology. Compared with the infrared(fiber) laser, spotlight of 355nm UV light is very small. Due to this reason, it can greatly reduce the mechanical deformation of the material and heat processing influence is very small. So UV laser is  mainly used for ultra-fine marking and engraving,  especially suitable for food, pharmaceutical packaging materials marking, digging micro holes, high-speed division of glass materials and complex graphics cutting of silicon wafer applications.

Green laser marking machine is one kind of laser marking equipment. It is mainly used in glass and the surface and internal sculpture of crystal products. so it is often called laser inner engraving machine. Green marking machine is a common type of laser marking machine.

Green laser marking machine also uses side pump. but different from the semiconductor side pump laser marking machine, it has obvious advantages: the wavelength of 532nm green laser output, After focusing,  the spot diameter is smaller and energy is more concentrated.So Green laser equipment is more suitable for the surface engraving of glass products, such as mobile phone screen, LCD screen, optical device (such as optical lens, etc.), automobile glass and so on. At the same time, it can be applied to surface processing or coating film processing of the vast majority of metal and non-metallic materials, such as hardware, ceramics, glasses watches and clocks, PC, electronic devices, all kinds of instruments, PCB board and control panel, nameplate panels, plastic and so on.
