Working principle of laser marking machine: lamp pump YAG laser marking machine: Xenon lamp is used as the energy source (excitation source), Nd: YAG is used as the laser production medium, sending out a specific wavelength can promote the level conversion of the production working substance to release the laser, amplifying the laser energy, forming a laser beam, and processing into materials.
CO2 gas is used to charge the discharge tube as the medium for laser generation. When a high voltage is applied to the electrode, a glow discharge is generated in the discharge tube, so that the gas molecules can release the laser. The laser energy is amplified to form a laser beam for processing materials.
·Semiconductor side pump YAG marking machine: the Nd: YAG medium is pumped by a semiconductor laser diode with a wavelength of 808nm, so that a large number of inverted particles are produced in the medium under the action of Q switch, forming a giant pulse with a wavelength of 1064nm laser output, and the electro-optic conversion efficiency is high.
·Semiconductor end pump YAG marking machine: the semiconductor pump light (808nm) is directly pumped from the end of the laser crystal, and the laser is output through the optical lens group. The efficiency of optical conversion is greatly improved.
·Optical fiber marking machine: optical fiber directly outputs laser.
3. Different marking range and prices
·CO2 marking machine: mainly used for non-metal (wood, acrylic, paper, leather, etc.), low price.
·Green marking machine, UV marking machine: mainly used for high-end ultra-fine IC and other products. The price is high, the product is customized.
·Light pump YAG marking machine: mainly used for metal, plastic and other low demand products. The price of laser marking machine is moderate.
·Semiconductor side pump marking machine: same as lamp pump YAG marking machine, but with stable price and moderate price.
·Semiconductor end pump marking machine: lamp pump like YAG marking machine is stable and energy-saving, but for high-end production, the price is high.
·Optical fiber marking machine: fine marking, power saving, maintenance free, for mobile phones, buttons and other high-end products. The price is very high.
In short, these techniques are very useful for marking fiber laser marking machines. Operators need to be familiar with and master! I also hope that colleagues can see this and get some help.
