1, the laser wavelength is different
• Green laser marking machine: 532nm
• Lamp 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, the working principle is different
• Lamp-pumped YAG laser marking machine: Xenon lamp is used as the energy source (excitation source), ND:YAG is used as the medium for generating laser light. The specific wavelength can be used to promote the production level transition of the working substance to release the laser, and the laser energy is amplified. A laser beam is formed that is processed into the material.
• CO2 laser marking machine: CO2 gas is used to charge 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 amplify the laser energy. A laser beam is formed that is processed into 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, electro-optical conversion efficiency high.
• Semiconductor end pump YAG laser marking machine: The semiconductor pump light (808 nm) is pumped directly from the end face of the laser crystal, and the laser is output through the optical lens set. The light conversion efficiency is greatly improved.
• Fiber laser marking machine: Directly output laser from fiber.
3, the scope of the mark and the price are different
• CO2 laser marking machine: mainly used for non-metal (wood, acrylic, paper, leather, etc.) at a low price.
• 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.
• Semiconductor side pump laser marking machine: It is the same as the lamp pump YAG laser marking machine. It is stable and the price is moderate.
•Semiconductor end pump laser marking machine: It is the same as the lamp pump YAG laser marking machine. It is stable and energy-saving, but it is used for high-end production and has a high price.
• Fiber laser marking machine: fine marking, power saving, maintenance-free, for high-end products such as mobile phones, buttons, etc., the price is high.
