Temperature Remains Relatively Constant During Processing Laser Pointer
A 10,000-watt power laser pointer is emitted from a 100 μm fiber core diameter. Its power density can be imagined. Generally speaking. The path through which the laser is transmitted is composed of fiber end mirrors, QBH or QD interfaces, collimating and expanding beam groups, zoom systems, focusing lenses, and lower protective lenses. In view of the ultra-high power density, optical lenses on all the above paths are proposed. Strict cleanliness and temperature rise requirements, the entire optical path must be strictly sealed, there must be no medium exchange with the outside world, and optical devices must be installed and cleaned in a clean space. In addition, the pressure of the cooling circuit in each link. Flow rate, order of water flow in and out, and water temperature are also important. Ensure that the temperature remains relatively constant during the laser pointer cutting process.

Application
usually. Laser pointer cutting must have a knife hole first. Especially when cutting thick plates. The quality of perforation is very important. Excellent perforation is the basis for ensuring the stability of the beam and airflow. For 10,000-watt laser cutting, the zoom perforation technology controls the relative distance between the beam expander group and the focusing lens through a servo motor to achieve positive and negative focusing spots. The change in defocus amount requires negative defocus for cutting stainless steel, aluminum and aluminum alloy, brass and copper. The larger the thickness, the deeper the negative defocus. Servo-controlled "double-convex-double-concave-double-convex" ZOOM lens group is used to achieve gradation or stepless focusing, high-speed dynamic zoom perforation, and cutting without slant on the cut surface. Using beam shaping technology. Laser pointer mode automatic conversion control technology, energy density calculus technology. Realize "bright cut" of large thickness stainless steel and highly reflective materials.
