3W DPSS UV Laser Module
1. What’s UV Laser Marking Machine?
UV laser is very ssuitable to creat high-contrast markings on highly sensitive products. UV laser achieves high-contrast etchings on sensitive products through a photochemical effect. The heat input is very low so that sensitive materials such as medical plastics, silicones, white polyamides, colored tubes, cables or glass can be etched without damaging the product surface. It's a laser with the short wavelength 355nm to generate an intense energy beam breaking the molecular bonds and vaporize the substrate leaving a permanent mark without contacting the substrate. It is very suitable for sensitive and critical material(such as plastic , leather, etc.) marking with the advantage of its "cold marking" methods. Because it offers a higher absorption rate than fiber and CO2 lasers and are less likely to burn the surrounding material because they produce less heat. This is why UV laser is also referred to as “cold processing method”, while fiber and CO2 lasers are called as ‘thermal processing method’. Fiber / CO2 laser marking machine can alter or even burn some heat-sensitive materials, like plastic, leather, etc. This is because the laser energy is not fully absorbed, allowing too much light to pass through without marking the material. You’re left with indecipherable logos, unreadable barcodes, or damaged parts.
2. Product Description
- The laser generates 355nm UV laser with average output power ＞3W@30KHz;
- Client can choose laser crystal YVO4 or YAG according to actual need to meet final tech requirements;
- The laser is filtered twice inside laser resonator, besides client can opt intracavity primary beam expanding, lowering damage possibility of brewster window;
- The laser has an integrated driving circuit board inside. When connecting with stabilized voltage power supply, UV laser will be generated, improving the operation convenience and laser stability;
- The laser supports air cooled mode, it has a high effective aluminum cooling module with 7 fans and short wind pathway, guaranteeing quick cooling effect and device work normally;
- Adopting non-adjusting-frame manufacturing tech, the mechanical performance is more reliable and can work stably longer.
