We have primarily a comparison between the Diode Pump Laser Marking Machine and YAG Lamp Pump Laser Marking Machine.

Both of Diode Pump Laser Marking Machine and Lamp Pump Laser Marking Machine produce laser light on basis of Nd:YAG(Neodymium-doped Yttrium-Aluminum-Garnet) crystal as laser material that can be converted from the visible light of 808NM to invisible laser light with a wavelength of 1064nm, but another factor of the output laser light is laser pump source which can make the crystal rod put out laser light, the Diode Pump Laser Marking Machine send out light waves of 808nm by the use of semiconductor diode, and the Lamp Pump Laser Marking Machine use krypton lamp to send out light. Therefore, the conversion efficiency of the Diode Pump Laser Marking Machine is much higher than the Lamp Pump Laser Marking Machine.

Advantages of Diode Pump Laser Marking Machine are as follows:

Third, Diode Pump Laser Marking Machine will have a better marking affects.

Since almost all semiconductor diode transmit one same wavelength light, as a result, the laser beam has better monochrome, better marking mode, more energetic and better marking results.

Second, the diode laser marking machine has much smaller size than the YAG Lamp Pump Laser Marking Machine.

It is said that the Diode Pump Laser Marking Machine produce less waste energy than YAG series Lamp Pump Laser Marking Machine, smaller cooling system is enough, usually a refrigerator may be sufficient, while the Lamp Pump Laser Marking Machine will need more than two or more cooling system and cooling pump for providing a water flow.

Therefore, the Diode Pump Laser Marking Machine produced less noise during working than the Lamp Pump Laser Marking Machine,while large cooling unit will produce more energy from YAG Lamp Pump Laser Marking Machine, especially in summer high temperature, excess calories will make the working environment worse and worse, and the increasing air regulator to balance temperature will no doubt increase the production costs.

Along with the development of laser technology, Laser Marking Machine plays an especially important part in marking processing area. Laser marking machine is much more effective than traditional marking processing equipment.

Laser marking machine is the greatest invention of the twentieth century, and Laser Marking Machine has played a unique role in science and modern technology from the first introducing of 1960, laser marking machine plays an important role in the fields such as new technology, automotive, environmental monitoring, communications, defense and security and so on.

Because of its excellent optical properties of the laser marking machine, namely the high brightness, high resolution, high consistency and coherence, laser marking machine has a permanent place in the metallurgical industry was uninhabitable.

Along with the improvement of the laser power and application of the line engine, the processing of laser marking machine is in rapid progress. The increased power of laser marking machine means that the laser marking machine can not only process thick steel plate, but also in high speed processing.

The importance of Laser Marking Machine is certainly no doubt, which is a powerful complementary part of the traditional marking process, has solved many problems of the conventional process. For example, the laser marking machine has been possible to process material in various complex shape and small size, such as nonmetallic materials as ceramic, all of the complex processing is enough for the laser marking machine to solve.

In particular, Laser Marking Machine is a quite good choice in marking processing area.

Laser marking technology in glass processing industry

It has been a long time that the laser marking technology used in glass marking process. How to improve the marking quality has constantly a big problem. With the development of the sealed-off CO2 Laser Marking Machine, usually a 25w CO2 laser marking machine is enough, has made it no longer a problem to worry about any damage during the laser marking work on glass.

Comparing with solid state CO2 laser marking machine and other traditional marking tools, this CO2 Laser Marking Machine has made us no need to worry about the quality problem of glass products. According to destroy the glass surface to mark through laser marking machine, it is always admitted to have a certain number of cracks, while over power mark will make unclear mark on glass, and more serious thing is that the internal material of glass will become loose.

Generally we have three ways to control the cracks number and crack type of glass surface: the first is the adoption of multiple laser radiation, the adoption of discrete points to get ring cracks is the second methods, and the third method is to get crack type crack.

When we decide which method to use while using the CO2 Laser Marking Machine, we should have a clear and careful analysis of the glass type and pattern requirement. The proper use of CO2 laser marking machine in glass marking process will help us get fine and high quality laser mark.
