How to distinguish fiber laser marking machine

The difference between fiber laser marking machine, how to distinguish various types of fiber laser marking machine, I will introduce to you.

1. The laser wavelength is different

·Deep UV laser marking machine: 266 nm

·Green laser marking machine: 532nm

· Lamp pump YAG laser marking machine: 1064nm

·Semiconductor side pumped YAG laser marking machine, semiconductor end pumped YAG laser marking machine: 1064nm

·Fiber laser marking machine: 1064nm

·CO2 laser marking machine: 10.64um

2. The working principle is different

· Lamp-pumped YAG laser marking machine: Using krypton lamp as the energy source (excitation source), ND: YAG as the laser generating medium, emitting a specific wavelength can promote the energy level transition of the working substance to release the laser, and the laser energy is amplified It forms a laser beam for material processing.

·CO2 laser marking machine: Use CO2 gas to be charged into the discharge tube as the medium for generating laser. When a high voltage is applied to the electrode, a glow discharge is generated in the discharge tube, which can release the laser light from gas molecules and amplify the laser energy. It forms a laser beam for material processing.

·Semiconductor side-pumped YAG laser marking machine: Use a semiconductor laser diode with a wavelength of 808nm to pump Nd: YAG medium, so that the medium produces a large number of inverted particles to form a giant pulse laser output with a wavelength of 1064nm under the action of the Q switch, and the electro-optical conversion efficiency high.

·Semiconductor end-pumped YAG laser marking machine: Pump the semiconductor pump light (808nm) directly from the end face of the laser crystal, and output laser light through the optical lens group. The line light conversion efficiency is greatly improved.

·Fiber laser marking machine: output laser directly from optical fiber.

3. The marking range and price are different

·CO2 laser marking machine: mainly used for non-metals (wood, acrylic, paper, leather, etc.), at a low price.

·Green laser marking machine, ultraviolet laser marking machine: mainly used for high-end and ultra-fine IC products. The price is higher, and the product is customized.

· Lamp pump YAG laser marking machine: mainly used for low-demand products such as metal and plastic. The price of laser marking machine is moderate.

·Semiconductor side-pumped laser marking machine: It has the same use surface as the lamp pumped YAG laser marking machine, but it is more stable and affordable.

·Semiconductor end-pumped laser marking machine: It has the same use surface as the lamp pump YAG laser marking machine, stable and energy-saving, but it is used for high-end production and the price is higher.

·Fiber laser marking machine: It is used for high-end products such as mobile phones, buttons, etc. The price is high.

In short, these tips are of great help to the marking effect of the fiber laser marking machine. To be familiar with and master these is a must for the operator! I also hope that the practitioners in the same industry will see these and have a little help.
