In the material after years of laser pointer pen optical products and infiltration of anterior posterior segment, a variety of optical materials laser pointer pen is important for all kinds of collocation in laser application. How collocation can achieve its best performance, in order to maintain the stability and service life, for example, we often say that the quartz material, the design is that of quartz, but there are dozens of concrete material hundreds of kinds of difference between the price and laser pointer pen performance of the layman may not know, but the impact on the application of laser system can be very large.
The special laser pointer pen requirements of the fiber laser is mainly manifested in: lens material selection, because the power of fiber laser now used more and more high, the current conventional flint or crown glass, due to its high laser pointer pen absorption rate and high inflation rate has been unable to heat the applicable requirements. But by now the quartz materials. Because the refractive index is too low, there are many limitations in the system design. And through the band in the 1064nm material of these problems are common. So the lens substrate selection is very important for fiber laser pointer pen.
Low power CO2 laser pointer pen engraving equipment, low power CO2 laser marking equipment, low power fiber laser marking equipment, YAG laser pointer pen marking and welding equipment, UV laser marking equipment, however, in high power laser pointer pen applications, laser optical components produced by domestic manufacturers is not up to the requirements of the application, the main the problem is that the damage threshold of coating laser optics and firmness were not enough, but also can not withstand high power or high energy laser.
Another key point is coating, coating the fiber laser pointer pen damage threshold requirements are very high, the film is firm and high damage threshold is the key point of application. The lens has a good performance in these three aspects, the highest can be applied in 8000W fiber laser pointer pen.
