Can nanosecond solid-state UV lasers produce color?

Ultraviolet laser marking machine belongs to a series of products of laser marking machine, but it is developed with 355nm ultraviolet laser. Compared with infrared laser, the machine adopts third-order intracavity frequency doubling technology. To a large extent, the mechanical deformation of the material is reduced and the thermal influence of processing is small, because it is mainly used for ultra-fine marking and engraving, especially suitable for marking food, pharmaceutical packaging materials, drilling micro-holes, high-speed division of glass materials, and high-speed processing of silicon wafers for complex pattern cutting and other applications.

Can the principle of UV laser marking machine achieve color marking?

Advantages of UV laser marking machine:

Ultraviolet laser can carry out ultra-fine marking and special material marking due to the extremely small focusing spot and the small heat affected zone of laser marking machine processing. It is the first choice for customers who have higher requirements for marking effect. In addition to copper materials, UV lasers are suitable for a wider range of materials. Not only the beam quality is good, the focusing spot is smaller, and ultra-fine marking can be realized; the scope of application is wider; the heat-affected area is extremely small, no thermal effect will occur, and there will be no material scorching problem; marking speed and efficiency are high; the performance of the whole machine Stable, small size, low power consumption and other advantages.

Can the principle of UV laser marking machine achieve color marking?

Industry application:

The UV laser marking machine is mainly based on its unique low-power laser beam, which is especially suitable for the high-end market of fine processing of ultra-fine UV laser marking machine. The surface marking of packaging bottles of cosmetics, medicines, food and other polymer materials, the effect is very good. Fine, clear and firm marking, better than ink coding and no pollution; flexible pcb board marking and dicing; silicon wafer micro-hole and blind-hole processing;

Can laser marking be colored? In recent years, with the rapid development of laser technology, the application level of laser technology has gradually improved. Color laser marking is a new type of laser marking process. Mainly acting on stainless steel material, it can engrave colorful patterns.

Can the principle of UV laser marking machine achieve color marking?

The study found that the key to realizing the colorization of the metal surface lies in the strict control of the pulse energy end-pumped laser marking machine and the pulse width of the laser. High frequency, low pulse energy lasers are more suitable for this application, and fiber lasers are the most suitable choice due to their adjustable pulse parameters and good beam quality. By tightly controlling heat injection, fiber lasers are able to print colored marks on metal surfaces.

Color laser marking machines differ from ink deposition techniques and those that apply colored powders or films. More advanced lasers can change the color of plastics. The typical physical effect is related to the thermal decomposition of polymers in an oxygen environment. In contrast, various colors can be produced on the surface of metal raw materials.
