兴发娱乐首页登录:为什么光纤激光打标机的使用寿命会这么长?

We all know that fiber laser marking machine is the life of about 10W hours, and semiconductor laser marking machine is the life of only about 2W hour, why fiber laser marking machine life would be so long?

Semiconductor laser marking machine with the extension of working hours, the laser threshold current increases slowly, resulting in a semiconductor laser marking machine laser degradation. Using semiconductor laser die is extremely small, high operating current density and power density, and as a single crystal semiconductor material laser material and more prone to defects that evolved under the influence of electrical and optical, causing device performance degradation. Laser mirror is formed by cleaving process, the mirror itself is environmental conditions and pollution will also result in laser performance degradation. Die bonding is a key technology, the die solder on the heat sink and the heat sink from the active to only a few microns; a semiconductor laser work may have a fever, if too much solder will occur when heated slowly climb the semiconductor laser short-circuit, resulting in degradation of the laser. On the other hand, any laser marking machine equipment require special attention and maintenance, in fact, a semiconductor laser marking machine life is not fixed, as long as we usually pay attention to maintenance, then he can extend its useful life. Fiber laser marking machine is also true, as long as usual periodic cleaning, cleaning, maintenance and other work, whether or semiconductor laser marking machine fiber laser marking machine, its service life can be in the original substantially longer appropriate.

With the development of domestic production of fiber laser manufacturers more and more, more mature technology, fiber laser marking machine prices have been falling, the semiconductor laser marking machine gradually replaced by optical fiber. Of course, any laser equipment is required to maintain our intentions, whether or fiber laser marking machine semiconductor laser marking machine, are to be so.
