Green laser technology as a core driving force in the field of industrial manufacturing, itself is also constantly moving forward. In summary, the development trend of green lasers is developing in the four directions of "faster, higher, better and shorter".
Green laser beams often provide low-voltage alternatives for mechanical printed circuit board machining, such as milling or automatic board cutting. However, green lasers have the advantage that other green lasers do not have, that is, they can limit thermal stress. This is because most green laser systems operate at low power. What is the development trend of green lasers?
The wavelength of a green laser is shorter than that of visible light, so it is invisible to the naked eye. Although you cannot see these green laser beams, it is these short wavelengths that allow the green laser to focus more precisely, thus producing extremely fine circuit characteristics while maintaining excellent positioning accuracy.
In addition to the short wavelength and low workpiece temperature, the high energy photons present in ultraviolet light allow green lasers to be used in large PCB circuit board combinations, ranging from standard materials such as FR4 to high frequency ceramic composites and flexible PCB materials including polyimides.
Future potential market
What are the advantages and disadvantages of green lasers in the future market? It has always been a topic of concern.
Green laser cleaning: With the enhancement of environmental awareness, a variety of environmental cleaning technologies came into being, green laser cleaning technology is one of them.
Green laser cleaning The use of high-energy green laser beam and the workpiece surface to remove the substance interaction, instantaneous evaporation or stripping, without a variety of chemical cleaning agents, green pollution-free. Can be used to remove paint, oil, oxide layer, cleaning screw, rust, weld cleaning and so on.
Green laser cleaning has a huge market space in microelectronics, construction, nuclear power plants, automobile manufacturing, medical care, cultural relics protection, steel rust and mold decontamination, automobile manufacturing, construction and other fields.
Metal 3D printing market: Metal 3D printing, also known as additive manufacturing, usually uses selective green laser cladding (SLM) technology, which uses green laser energy to melt metal powder layer by layer, and finally make the desired shape.
In 2016, the sales of SLM systems exceeded 1000 units, of which the green laser sources used are mainly fiber green lasers, disc green lasers /CO2 green lasers and femtosecond fiber green lasers, with a power range of 30W to more than 1kW. The precision of 3D printing is also getting higher and higher, and the resolution of the printed fine structure has reached the micron order.
Green laser radar: The development trend of green laser in the next five years will grow steadily, and the main driving force for market growth comes from the fields of drones, autonomous vehicles, robotics, military and security.
Green laser lighting: Part of the green laser lighting market is automotive green laser lighting, mainly automotive headlights. BMW, Audi and other well-known car manufacturers have adopted green laser lighting systems. Another part of the market is safe green laser lighting, such as providing warning signs for people riding in night environments.
In order to adapt to the development trend of industrial processing green laser, our company independently developed 355nm end-pumped Q-switched green laser. The product has the advantages of small size, compact structure, light work, low power consumption, green laser as the basic mode, good beam quality and high peak power. According to the use environment, this series of products adopt water-cooled form, the excellent resonator design to obtain high power stability, pulse sequence stability, completely and can be adjusted and controlled at any time green laser power power and repetition frequency output, fully meet the requirements of industrial precision machining.
