Why UV lasers are more expensive than fiber lasers

The structure of the UV laser marking machine is the same as that of the fiber laser marking machine. It is composed of original parts such as surgical mirrors, so how many times the price of UV laser marking machine is the price of fiber laser marking machine?

The optical devices of the fiber laser marking machine and the ultraviolet laser marking machine are not universal. The wavelength of the ultraviolet laser is 355nm, the wavelength of the fiber laser is 1064nm, and the wavelength of the ultraviolet laser is the wavelength after frequency doubling based on the wavelength of 1064nm through technology The technical difficulty is higher, which also causes the price of ultraviolet lasers to be several times that of fiber lasers;

Compared with the coating thickness and material of the fiber laser marking machine, the galvanometer and lens of the ultraviolet laser marking machine are different, so they cannot be used universally. The galvanometer and lens of the ultraviolet laser marking machine are also more expensive. Of course, the conventional galvanometer on the market The price difference between the two types of equipment is not large, and the main price difference is in the ultraviolet laser and the fiber laser.

On the other hand, UV laser marking machines have relatively higher requirements on the environment, especially water-cooled lasers, which need to be kept at a constant temperature, so there are higher requirements for accessories. Due to the extremely small focusing spot and the small processing heat-affected zone, the UV laser can perform ultra-fine marking and special material marking. It is the preferred product for customers who have higher requirements on the 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, and there will be no thermal effect and no material burning problem.

The overall combination makes the price of the UV laser marking machine relatively expensive, which is mainly reflected in the high cost of the UV laser and the large labor cost in the later stage.

The price of UV laser marking machines is mainly determined by the price fluctuations of UV laser manufacturers. For example, there were no UV laser manufacturers in China in the early years, and a 3w imported UV laser also required hundreds of thousands. Breakthrough, the price of 3w UV laser has also dropped significantly. So far, the pure imported top UV laser only costs tens of thousands of RMB. Therefore, the price trend of UV laser marking machines currently depends on the development of the overall domestic UV laser manufacturers and the development of market applications.
