1. Lamp-pumped YAG laser marking machine: Krypton lamp is used as the energy source (excitation source), ND: YAG is used as the medium for generating the laser, and emitting a specific wavelength can promote the production energy level transition of the working substance to release the laser, and amplify the laser energy Then a laser beam is formed to process the material.
2. CO2 laser marking machine: CO2 gas is used to charge the discharge tube as a medium for generating laser light, and a high voltage is applied to the electrode, and a glow discharge is generated in the discharge tube, causing the gas molecules to release laser light, and the laser energy is amplified. Forms a laser beam for material processing.
3. Semiconductor side pump YAG laser marking machine: use a semiconductor laser diode with a wavelength of 808nm to pump the Nd: YAG medium, so that a large number of inverted particles are generated in the medium to form a giant pulse laser output with a wavelength of 1064nm under the action of Q-switching, electro-optical conversion efficient.
4. Semiconductor end-pumped YAG laser marking machine: pump the semiconductor pump light (808nm) directly from the end face of the laser crystal, and output the laser through the optical mirror group. The line light conversion efficiency is greatly improved.
5. Fiber laser marking machine: The laser is output directly from the optical fiber.
6. Green laser marking machine: The green laser marking machine is developed by using the most advanced laser pumping technology (side pumping or end pumping) with a wavelength of 532nm in the world.
