All lasers types are unique, each one will suit different materials and tasks. In fact, even within one type of laser source technology there are variations in quality, type, power and versatility.Get more news about Uv Laser Marker,you can vist our website!

So how do you know which one to use?

To make it digestible, we are going to split it into the main three types of lasers. They are all capable of marking or engraving to some degree, but not all of them will work effectively, so we will look at the pro’s and cons of each one.

Further down the page there is information about the technology, how it works and a quick reference table. If you want to know what best matches your material then feel free to call us or drop our team an email.
UV lasers work a little differently to their CO2 or Fibre based siblings as they do not damage the materials surrounding surface, using a far lower power form of marking. This makes them the best of the bunch when it comes to “marking”, suitable for anything from fruit, to glass, teflon, diamond, silicone, plastic and precious metals. You really can mark almost anything with a UV laser!

How do UV laser marking systems work?
Operating at 355nm, UV lasers have a much shorter wavelength than the other technologies here. Using a process termed “cold processing”, UV lasers shoot high-energy photons in the ultraviolet spectrum that break the chemical bonds in the material which causes the material to undergo non-thermal process damage. This process does not produce thermal deformation (heat damage) on the inner layers and nearby areas of the target area.

A UV laser’s wavelength is one-third of standard wavelength lasers, therefore often referred to as third-harmonic generation (THG) lasers. This wavelength is achieved by passing a standard wavelength laser at 1064 nm through a non-linear crystal, reducing it to 532 nm, this is then passed through another crystal, reducing its wavelength further, down to the working 355 nm.

In summary, the UV marking process is extremely fine and controlled, making it great for delicate or accurate work. However, due to the process this technology employs, a UV laser marking system is not normally suitable for engraving or cutting.
