Laser marking machine principle and features

Laser marking principle is the use of high energy density laser shines on the workpiece, so that the surface materials or onset of vaporization chemical reaction color change, leaving a permanent sign marking approach. Laser marking can play a variety of characters, symbols and drawings, etc., the characters can be on the order size from millimeters to microns, which for security products has a special meaning. Wherein the primary types of equipment on the market of the following categories.
Fiber laser marking machine: the fiber laser output directly. Semiconductor end pump YAG laser marking machine: directly from the end surface of the laser crystal semiconductor pump light (808nm) pumped by laser light generating optics output. So that the row of light conversion efficiency is greatly improved.
Nonmetallic CO2 laser marking machine: use CO2 gas filled discharge tube as the laser medium occurrence, when a high voltage electrode, a glow discharge occurs in the discharge tube, gas molecules can release the laser, the laser energy to expand after the formation of the information processing laser beam. Lamp-pumped YAG laser marking machine: the choice of krypton lamp as energy source (source of encouragement), ND: YAG laser medium occurrence as announcing a specific wavelength can promote job material production level transition release of the laser, the laser energy to expand after the formation of the data-processing laser beam. Semiconductor side pump YAG laser marking machine: the use of a wavelength of 808nm semiconductor laser diode-pumped Nd: YAG medium, the medium particle formation occurs much rotation giant pulse laser output wavelength of 1064nm under the influence of Q-switch, electro-optical conversion efficiency.
Features:
Laser marking machine construction progress in line greatly improved: the choice of the optical system fully sealed structure with optical path preview and focus indication functions, appearance more beautiful, more convenient operation; the machine is equipped with the latest external water cooling system, operating noise low temperature conditioning of high precision, long-term operation of the machine provides a reliable protection. XD / razor Some models can also be used for co-production lines and automated production line equipment.
It is based on the principle of laser marking, metal, plastic, semiconductor materials such as laser marking process. In the mold, home appliances, mobile phones and other industry has played a higher realm. On security played a very good effect, aesthetic level is amazing.
