YAG Laser Marking
YAG lasers are the most commonly used type of laser for etching, marking and engraving applications as well as cutting or welding steel. These lasers are suitable for micromarking as well as deep engraving, annealing and ablation processes, making them a versatile tool. YAG (yttrium aluminum garnet) lasers feature a standard 1064 nm wavelength and emit a single infrared beam of high energy light to a focused area.
YAG laser engraving has a wide range of capabilities and can be used to mark metal and plastics with:
- QR codes
- Serial numbers
- Expiration dates (for food and beverages)
- Product identification
YAG laser marking provides high speed and accuracy and is an ideal solution for most metals, ceramics, and plastics, including painted or coated surfaces. Due to the intensity of the wavelength, one important factor when considering YAG laser marking is that the materials must also be able to tolerate the increase in surface temperature generated by the laser. Contact us to discuss your laser marking project and to see if YAG lasers fit the demands of your application.
The Difference Between YAG Lasers and CO2 Lasers
CO2 lasers are similar to YAG lasers, except they have a 10.6 μm wavelength, which is 10 times larger than the beam emitted by YAG laser marking machines. YAG lasers also provide more precise laser marking than CO2 lasers because they have a narrower kerf. Due to having a significantly longer wavelength, CO2 lasers are not as easily absorbed by metals but are well-suited for organic materials such as rubber, wood, and acrylic.
YAG Laser Marking Services for Metals and Plastics
Arrow Cryogenics offers YAG laser engraving services for a range of applications and materials. YAG lasers are ideal for product identification and trackability because they produce a highly legible and tamper-resistant marking that is resistant to high temperatures. It is more reliable and bio-compatible than printing with ink and since there is no need to regularly replace an etching tool, it can be more cost-effective than other marking and engraving methods.
We work with a number of different laser marking machines and even dedicate machines to specific materials to help produce the best results possible. Arrow Cryogenics has the capability to work with a diverse array of products and materials. We provide YAG laser marking services to various industries including:
- High-end Technology
Our team will work with you to determine whether YAG laser marking it the appropriate solution for your laser engraving project. If YAG laser engraving is not the appropriate application, we also offer green laser marking and UV laser marking services.
