Laser Technology in the Field of Laser Marking

Among the various types of lasers, CO2 and Fiber lasers are widely used in the marking process. The next generation of lasers is the Nd  YAG laser, which could add color to the mark, allowing for greater design flexibility. While CO2 lasers and Fiber lasers have been the mainstay of laser marking, other types are becoming more popular. In addition to fiber and CO2 lasers, UV lasers are also gaining ground visit this website

CO2 laser

CO2 laser marking uses the energy of CO2 gas in a sealed tube to create a highly concentrated beam. The CO2 laser operates in the mid-infrared portion of the light spectrum, which is outside the range of human vision. It has a high thermal effect and is an excellent choice for marking organic materials. CO2 lasers are available for both benchtop and mark-on-the-go installations.

MECCOmark CO2 Laser uses the latest technology to mark date codes, serial numbers, and product identification on a wide range of materials. The CO2 laser is the most cost-effective solution in laser marking, and its embedded control technology eliminates the need for PLC custom programming. This machine is also able to mark non-contrast plastics and is able to remove ink to produce date coding.

Fiber laser

A fiber laser is a type of high-power, high-frequency light source. Its unique characteristics make it a great choice for laser marking. The fiber laser can mark materials with a wide range of contrast and can also be used to mark images and text. The fiber laser resonator combines a bragg grating and a gain medium to generate the right wavelength for the application. Fiber laser technology is the most widely used technique for engraving and marking, and it can be used to mark text, images, logos, and even change color. Its durability is also unsurpassed and its use is practically maintenance-free.

Unlike other laser technologies, fiber lasers do not require any sensitive optical equipment and can generate the beam with great stability. Their light source is composed of multiple fibers connected to each other, so the laser beam is stable and can be precisely focused. Fiber lasers have many applications in a wide range of industries. They are flexible and can work on delicate medical equipment as well as strong auto components. The possibilities are virtually endless for fiber lasers.

Nd YAG laser

The M2 value of an Nd:YAG laser is higher than that of a fibre laser. The M2 value reflects the beam quality, allowing for the smallest spot size relative to optics and wavelength. Therefore, an Nd:YAG laser can produce the highest quality beams for laser marking. The M2 value is a key parameter when choosing a laser for laser marking.

This wavelength is outside the visible spectrum, but infrared. Because of this, it has a wide variety of practical applications in military, medical, and scientific fields. Its output power varies depending on the pulse width and amount of power delivered to the flashlamp. It is the most common wavelength for laser marking, but may not be the most efficient option. In addition, Nd:YAG lasers may require a lengthy warm-up period and can damage materials.

Ultraviolet laser

There are many advantages of using an ultra-violet laser in the field of laser-marking applications. In addition to being able to process a wide range of materials, these lasers can also produce a precise, fine contour and engraving effect. This makes them an ideal solution for high-end marking needs. The laser beam illumination used to make them allows for ultra-fine engraving without mechanical stress or cracking. You can use the computer control to edit the text and group, as well as select standardized shapes for marking.

Another advantage of UV lasers is that they are able to mark a wide range of materials, including glass, silicone, and plastic. UV lasers are particularly useful for marking medical devices and solar panels, which are extremely thin and often require precise positioning and traceability. They are also able to mark moving objects such as microchips and solar panels. Lastly, UV lasers are easy to use and operate and do not require consumables.
