What is the difference between Ultra Violet Laser Diodes Source and fiber laser marking machine?

Many people will be curious when purchasing a laser marking machine, what is the difference between a UV marking machine and a fiber optic marking machine? How can I choose a processing tool that suits me?

Ultraviolet laser marking machine belongs to a series of products of laser marking machine, but it is developed with 355nm ultraviolet laser. The machine adopts third-order intracavity frequency doubling technology. The mechanical deformation of the material is greatly reduced, and the thermal influence of processing is small.

The fiber laser marking machine uses a wavelength of 1064nm. Regarding the laser wavelength, generally the shorter the wavelength, the smaller the laser spot, the higher the precision, the smaller the heat-affected zone formed during processing, and the more exquisite the processing effect.

Fiber laser marking machines have been very popular, and they are mainly used in metal marking. They are generally not products with high precision requirements, such as marking depth and metal lettering. A welcome one, mainly depends on the configuration.

The UV laser marking machine belongs to the cold processing mode, which has a small thermal effect on the product and has almost no damage to the product. Therefore, it is very popular in terms of high precision. Some small or fine PVC products, which cannot be replaced by optical fibers, can be marked and produced by UV laser marking machines. Due to the unique advantages of this equipment, the price is higher than that of other laser marking machines. Standard machines are relatively expensive.

Nowadays, the fiber laser marking machine is the mainstream of the market in metal material marking. The radiation of the optical fiber is relatively large, and the radiation of the optical fiber is much smaller, so the optical fiber is relatively easy to be accepted by customers.
