   [Shenzhen Chenda Laser Marking Machine] How to distinguish different types of laser marking machines? First, take a look at the  difference in laser wavelengths:
Deep ultraviolet laser marking machine: 266nm
Green laser marking machine: 532nm
Lamp pump YAG laser marking machine: 1064nm
Semiconductor side pump VAG laser marking machine, semiconductor end pump YAG
Laser marking machine: 1064nm
CO2 laser marking machine: 10.64um

   [Shenzhen Chenda Laser Marking Machine] Secondly, the working principle is different:


Lamp-pumped VAG laser marking machine: using short lamp as energy source ( proud source), ND:YAG as the medium for generating laser, emitting special wavelength can promote the working material production level transition to release laser, after laser energy amplification A laser beam is formed that is processed into the material.
   CO2 laser marking machine: CO2 gas is used to break into the discharge tube as the medium for generating laser light。 When a high voltage is applied to the electrode and a glow discharge is generated in the discharge tube, the gas molecules can release the laser light, and the laser energy is amplified。 A laser beam is formed that processes the material。
Semiconductor side pump YAG laser marking machine: using a 808nm semiconductor laser diode to pump Nd:YAG medium, the medium generates a large number of inverted particles to form a giant pulse laser output with a wavelength of 1064nm under the action of Q switch, and the electro-optical conversion efficiency is high。 。
   Semiconductor end pump VAG laser marking machine: The semiconductor pump light (808 nm) is directly pumped from the end face of the laser crystal, and the laser is output through the optical lens group. The light conversion efficiency is greatly improved.
Optical fiber coating and marking machine: The laser is directly output from the optical fiber.
Furthermore, the price range of the marking machine equipment is different:
CO2 laser marking machine: mainly used for non-metal (wood, acrylic, long, leather), cheap。
Green laser marking machine, UV laser marking machine: mainly used in high-end ultra-fine IC and other 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 laser marking machine is moderately priced。 The semiconductor side pump laser marking machine: the same as the lamp pump YAG laser marking machine, but it is stable and the price is moderate。
   The semiconductor end pump laser marking machine: the same as the lamp pump YAG laser marking machine, stable and energy-saving, but used for high-end production, the price is higher.
Fiber laser marking machine: fine marking, power saving, maintenance-free, for high-end products such as mobile phones and buttons. The price is high.
   [Shenzhen Chenda Laser Marking Machine] In short, these tips are very helpful for the marking effect of the laser marking machine. It is necessary for the operation staff to be familiar with and master these! I also hope that peer practitioners will see this and have some help.
