Current Trends in the Laser Marking Industry

With the help of increased laser power, improved beam quality, higher speeds, and enhanced control systems, laser marking systems have expanded their capabilities and use across various industries. From shorter wavelength machines that make marking on more materials possible to the development of femtosecond lasers for ultrafast marking, the industry continues to make discoveries that expand marking abilities.

Lasers with Shorter Wavelengths for Achieving Better Accuracy

Using laser marking machines with shorter wavelengths helps to achieve better resolution and contrast on your materials. Examples of machines that have shorter wavelengths include systems featuring UV lasers and green lasers. Not only are these systems precise, but they also are compatible with a variety of materials, making them the perfect solution for diverse applications.

UV lasers are known for their ability to facilitate “cold marking,” which is a method that does not result in extreme heat stress being applied to the surface of an object. This is ideal for applications that involve softer materials like gold, silver, or copper.

Green laser marking is also designed to conduct cold marking on materials and is the best solution for materials that are not reactive to other wavelengths. Green lasers are often used to achieve foaming, which is used in some cases to mark plastic, rubber, and other similar materials.

Both of these laser types are ideal in a world where there is a high demand for clear and sustainable ways to create long-lasting marks on products. Whether the markings are used for traceability or aesthetic appeal, laser marking machines are ready to take on the challenge.
