For different purposes, different kinds of laser marking machines could be applied. Therefore, in the laser industry nowadays, there are multiple types of solutions for laser marking, which are fiber laser solution, green laser solution, and UV laser solution. So, what are these solutions exactly? Please let me introduce that to you in the following contents.
Here is the content list:

In recent years, fiber laser marking solution has become one of the most popular parts marking technologies that are used in the world. Fiber laser marking machines based on fiber laser solutions generally have a power range of 20 to 50 watts and are some of the most powerful laser marking machines on the market. These machines are ideal for deep etching or engraving. They can achieve good results on harder metals or require high-power systems with high light spots and low power points to achieve high resolution. The high beam quality and the small spot size of the larger lens allow fiber lasers to be used for small batch applications or for cutting very thin metals. There are many ways to adopt fiber laser solutions, for example, color mark and color removal, annealing, foaming, and carbonization. Advantages of fiber laser solution are that it can produce excellent beam quality and can be used on a variety of surfaces, and it lases marking machines based on such solution generally have great durability. Another feature of fiber laser solution is that it is so fast to operate that it is the fastest marking machine you can find on the market. There are disadvantages of it as well, for example, when marking some very thick or highly reflective materials, it cannot work quickly. It also cannot do very deep engraving on most metals.
laser marking machines that adopt green laser solutions are usually designed to mark materials with high reflectivity. They can also work on highly sensitive substrates such as silicon wafers. Green laser solution offers a very good work simplicity and a high work precision. laser marking machines that adopt this solution work in the green near-infrared visible spectrum (at 532 nm) and the power range of 5-10 watts. Green laser solution is very suitable for scribing or marking soft plastics, PCB boards, integrated circuit chips, and solar cells of various material compositions. The inherent advantages of the 532 nm wavelength include greater absorption of multiple materials and reduced thermal energy, allowing it to mark substrates that are simply not possible with other higher wavelengths. The green laser marking machines also transfer extremely low heat to the work surface, which is ideal for highly sensitive materials.
Ultraviolet (UV) laser solution represents an electromagnetic band with a wavelength of 10 nanometers to 400 nanometers. They are shorter than visible light, but longer than X-rays. Long-wavelength ultraviolet light is not considered ionizing radiation because its photons do not have the energy to ionize atoms. However, it can cause a chemical reaction to make the substance glow or fluoresce. As a result, the chemical and biological effects of ultraviolet rays are much broader than simple heating. Due to the interaction of ultraviolet rays and organic molecules, many practical applications of ultraviolet rays are also possible. Gas lasers, solid-state lasers, and diodes can be used to make machines that emit ultraviolet light, and lasers that cover the entire UV range can be used. Since the discovery of excimer lasers, it has been possible to use strong ultraviolet light. Researchers have explored and discovered the unique characteristics of this new light source. With the discovery and optimization of various phenomena involving the interaction of ultraviolet energy and materials, practical applications have emerged: Ultraviolet(UV) laser marking machine is the embodiment of this technology. UV laser machines are usually designed with a 355 UV laser wavelength and can mark various materials. They are very suitable for "cold marking" applications where lasers cannot be produced. UVC can mark materials such as plastics, ceramics, and glass without the need for additives. Due to the high beam quality, UVC can micro-mark electronic products, circuit boards, and microchips. They are also excellent on solar panels and precise medical device markings such as marking cylinders and syringes.
