Ultraviolet 40KHz 8w Laser Marking Engraving Machine For Glass Metal

Air-cooled Nd:Yag Laser

1. Product Description

• The laser generates 355nm UV laser with average output power ＞5W@40KHz;
• 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;
• Water cooling mode, high temperature resistance;
• Adopting non-adjusting-frame manufacturing tech, the mechanical performance is more reliable and can work stably longer.
• No consumables, low cost and low maintenance fee.

2. Comparison among 355nm UV Laser, 1064nm Fiber Laser and 10600nm CO2 Laser

1) The shorter the wavelength, the more concentrated the energy. The greater the energy, the more light that material will absorb. Greater absorption = Better quality mark. Compared with long wavelength 1064nm fiber laser and CO2 laser, 35nm UV laser can make better quality mark;

2) UV lasers are generally used for intricate, precise marks on the micro level. Their focused wavelengths allow for a high beam intensity and miniscule spot size;

3) UV laser are especially suitable for laser marking soft materials. 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’;

4) 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.
