It is said that the service life of fiber laser marking machine is very long, why is that?
I believe everyone has heard it! “The service life of fiber laser marking machine is very long.” If you have any knowledge or knowledge of laser marking machines, I believe everyone knows that the life of fiber laser marking machines is about 10W hours. There is no identification without comparison, so do you know what the life of a semiconductor laser marking machine is? Let me tell you that the life of a semiconductor laser marking machine is only about 2W hours.
So the question is, why does the life of a fiber laser marking machine be so long?
Here we will conduct a detailed analysis with you.
First, the semiconductor laser marking machine’s threshold current will increase slowly with the extension of the working time, which will cause the semiconductor laser marking machine’s laser to degrade. The semiconductor laser used has a very small die, high operating current density and high optical power density, and semiconductor single crystal materials, which are laser substances, are more prone to defects. These defects gradually develop under the action of electricity and light, resulting in device performance. Degradation. The mirror surface of the laser is formed by a cleavage process. The mirror surface itself is affected by environmental conditions and pollution will also cause the laser performance to deteriorate. Die welding is also a key technology. The die is welded on the heat sink, and the active source is only a few micrometers away from the heat sink; the semiconductor laser will heat up when it is working. If the solder is too much, it will slowly climb when heated, making the semiconductor laser A short circuit occurred, causing the laser to degrade.
On the other hand, any laser marking machine equipment needs our careful maintenance. In fact, the service life of semiconductor laser marking machines is not fixed. As long as we pay attention to maintenance, we can extend its service life. The same is true for fiber laser marking machines. As long as they are regularly cleaned, cleaned, and maintained, whether it is a semiconductor laser marking machine or a fiber laser marking machine, its service life can be appropriately extended.
As more and more domestic manufacturers develop and produce fiber lasers, and their technology is more and more mature, the price of fiber laser marking machines has also slowed, and semiconductor laser marking machines have gradually been replaced by optical fibers. Of course, any laser equipment requires our careful maintenance, whether it is a fiber laser marking machine or a semiconductor laser marking machine.
