Introduction and advantages of several common green laser marking machines

Laser equipment is indispensable in life. Many daily necessities have to use laser to achieve a corresponding effect. Then the laser equipment used is different in different materials and different needs. Let's take a look at the specific types of laser marking machines: lasers are divided into solid lasers (yttrium aluminum garnet YAG and yttrium vanadate YVO4), gas lasers (He-Ne laser, CO2 laser).

Carbon dioxide (CO2) laser marking machine

1. The carbon dioxide (CO2) laser marking machine uses CO2 gas as the activation medium to emit 10600nm light waves in the infrared region. There are two different types of lasers like Xinhuapeng.

Pulsed laser

2. Pulsed laser. Using the mask method, short-pulse laser energy is used to generate marks or graphics. However, because different markers require different masks, it takes a long time to change the markers.

Continuous laser

3. Continuous laser. It adopts the form of light pen with only one energy level, low technical requirements, low cost, simple equipment, but high output energy and high efficiency. It is widely used for laser marking and printing of plastics.

YAG laser marking machine

4. YAG laser marking machine. The activation medium is solid. The laser emits 1060nm light waves close to the infrared region. There are two types: continuous type and light pen type. By changing the output energy, laser beams of different intensities can be obtained. The marking process includes coking method (dark marking), foaming method (light marking) and ablation method (engraving marking), and the marking quality is excellent.

Excimer laser marking machine

5. Excimer laser marking machine. It can emit light waves in the ultraviolet range (100-400nm), and the activation medium is composed of a mixture of helium, argon, krypton, neon and chlorine, fluorine, bromine, iodine and other halogens.

532nm green laser 

The green laser marking machine is a high-tech equipment that uses high-energy and high-precision light beams to engrave permanent text and patterns on the surface of the object without contact and quickly. The green laser marking machine has the characteristics of super energy saving, no consumables, simple operation and fine marking effect. This series of models adopts imported foreign technology laser transmitter, high beam quality, fast marking speed, lifelong maintenance-free, stable and durable, and has a very high cost performance.
