How to distinguish between various types of fiber laser marking machine,Raymond will introduce to you.

1,the laser wavelength is different

Deep ultraviolet laser marking machine:266 nm

Green laser marking machine:532nm

Light pump YAG laser marking machine:1064nm

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

Fiber laser marking machine:1064nm

CO2 laser marking machine:10.64um

2, different working principle

Light-pumped YAG laser marking machine: Using a xenon lamp as energy source (excitation source),ND:YAG as a laser generating medium,emits specific wavelengths to promote the transition of the working substance production level to release the laser light,and the laser energy is amplified A laser beam is formed on the material.

CO2 laser marking machine:CO2 gas is used to fill the discharge tube as a medium for generating laser.When a high voltage is applied to the electrode, a glow discharge is generated in the discharge tube, so that gas molecules can be released and the laser energy can be amplified. A laser beam is formed on the material.

Semiconductor side pump YAG laser marking machine:Pumping Nd:YAG medium with a semiconductor laser diode with a wavelength of 808nm to generate a large number of inversion particles in the medium 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 pump YAG laser marking machine: pump the semiconductor pump light (808nm) directly from the end face of the laser crystal, and generate the laser through the optical lens group output. Make the light conversion efficiency greatly improved.

Fiber laser marking machine: Laser output directly from the fiber.

3, mark range and price are different

CO2 laser marking machine: mainly used for non-metallic (wood, acrylic, paper, leather, etc.), cheaper prices.

Green laser marking machine, UV laser marking machine: mainly used for high-end extremely fine IC and other products. Higher prices, product customization.

YAG laser marking machine for light pump: It is mainly used for low-demand products such as metal and plastics. The price of laser marking machine is moderate.

Semiconductor side pump laser marking machine: Same as the lamp pump YAG laser marking machine, but it is stable and affordable.

Semiconductor end pump laser marking machine: the same as the lamp pump YAG laser marking machine, stable and power saving, but for high-end production, the price is higher.

Fiber laser marking machine: Fine marking, power saving, maintenance-free, used in mobile phones, buttons and other high-end products. The price is high.

In short, these tips are very helpful for the marking effect of fiber laser marking machines. To familiarize with and master these, it is necessary for the operating staff! It is also hoped that peer practitioners will see this with some help.
