Despite the faster cutting speed and higher productivity of high-power solid-state lasers for metal 2D cutting, most metal manufacturers are excited, but it is still costly to control and manipulate the power of such lasers. Machine tool manufacturers continue to introduce higher power lasers. But in order to give full play to this advantage, they need to design to meet the stringent requirements of the red laser pointer system. The machine itself must be able to control the changes that occur with this high power cutting to ensure that the machining is not only fast and reliable, so that the manufacturer can give full play to the performance of the laser.

Therefore, the scientists by measuring the material to reflect the change in light to achieve the purpose of indirect observation - first with high-power laser pulse irradiation material, causing the material state changes, lag after a period of time after the launch of a weak laser pulse and the reflected light measurement. The energy of the first most powerful laser will quickly heat the material, while the reflection of the photon changes. And when the material begins to cool, the reflection begins to move closer to the normal value. Therefore, scientists can according to the reflected light to infer the dynamic state of the material changes. When the weak laser irradiation material, the material surface of some of the electrons will be ejected, scientists use electron microscopy to collect these electrons and the formation of images. In the case of weak laser irradiation, these electrons will gradually accumulate and eventually form a photo that reflects the electron distribution inside the material.

With the development of die-cutting technology and laser technology, the combination of the two, the use of laser to replace the traditional die-cutting die has a clear advantage. Laser die-cutting machine is a fully automatic laser cutting, no vibration deviation, high precision and stability. No need to make knife mold, by the computer directly control the laser cutting, and not limited by the complexity of the graphics, you can cut the traditional die can not complete the cutting needs. As the laser die-cutting technology is directly controlled by the computer, without the need to replace the knife template, can achieve different layout between the fast switching between the parts, saving the traditional die-cutting tool change and adjust the time, especially for short version, Cut processing. Laser die-cutting machine with non-contact characteristics, change live fast, short production cycle, high production efficiency.

In the use of laser pulse spot welding, the solder joints are prone to crack, resulting in decreased welding strength, stability is also greatly reduced. However, the traditional blue laser pointer beam is poor in mass, bulky, high maintenance cost and low photoelectric conversion efficiency, which restricts its consumption on the consumer electronics products to a certain extent. The traditional laser beam, YAG and other continuous laser welding aluminum alloy can avoid the crack. Applications. In particular, the structural parts of consumer electronics products have the characteristics of thin thickness, small volume and high precision. The traditional continuous laser welding is easy to produce large deformation, welding and burning.

In recent years, high-power high-beam quality of the laser in the line of materials processing industry applications have been rapid development, a wide range of lasers: different structures are divided into gas laser, solid laser, fiber laser, semiconductor 100mw laser pointer materials to support the mainstream of the processing industry; From far infrared to deep ultraviolet can cover (200nm ~ 20um), different industries will also use a different power range, different beam quality, different laser output and so on. In order to reduce the thermal effect in the field of processing thin film non-metallic materials, semiconductor wafer cutting, plexiglass cutting, drilling, marking and other fields, it is hoped that the small aperture effect and the high peak power, the role and position of the ultraviolet laser is so good and not alternative.
