What factors affect the spot size of the pipeline laser cutting machine

When the fiber laser cutting machine processes products, the size of the spot has a great influence on the processing effect and efficiency, and because the power of the total laser output is unstable, the size of the spot will also change. However, in order to improve the processing accuracy during laser cutting equipment processing, the light spot needs to be as small as possible. Let's take a look at what factors will affect the spot size of the fiber laser cutting machine.　　The light of the fiber laser cutting machine has the nature of waves, so it is inevitable that there will be diffraction phenomenon, which exists in all optical systems and can determine the theoretical limit of these systems in terms of performance. Diffraction causes the beam to expand laterally as it propagates. If an ideal' lens is used to focus a collimated laser beam, the size of the spot will only be affected by diffraction. The most important effect of 　　 diffraction is that it causes the spot size to increase linearly with the focal length, but inversely proportional to the diameter of the beam. Therefore, if the input laser beam diameter of a particular lens increases, the light spot will become smaller due to weaker diffraction. Moreover, if for a certain laser beam, when the focal length is reduced, the spot will also become smaller.　　 Wuhan Gaoneng Laser Equipment Manufacturing Co., Ltd. is a high-tech enterprise integrating Ru0026D, production and sales of professional laser complete sets of equipment.
