Energy density of laser pointer

It concentrates the pulsed intensity laser inside the glass to produce micron-level evaporation bursts. Use a calculator to control the spatial position of the glass burst point to form a vivid and colorful 3D image. Laser engraving technology engraves 3D patterns inside transparent materials such as glass to make the image more beautiful and realistic. During the manufacturing process, the laser pointer is also very clean and does not consume dust, toxic gas or water. To be able to engrave glass with a laser, its energy density must be greater than the critical value or threshold for breaking the glass, and the strongest energy density of any laser pointer at this point is the light spot, which is related to its size. The smaller the spot of the same laser, the greater the energy density generated at that position.

Science and technology are becoming more and more advanced, and people's lives are getting better and better. Laser technology is becoming more and more mature, and many people use or buy laser products, such as high power laser pointer, laser engraving machines, and laser stage performance props. In the city, crows will attack children and adults walking on the street. These crows not only attack people, but also steal things from people. Balcony hangers and small metal objects are the targets of the crows. Residents claimed that the balcony goods were stolen. At first they thought it was a thief, but the camera was the first to spot it. In addition, when crows enter the field and place stolen hangers and metal on the poles to build their nests, the poles often have problems. The problem is small, and some areas will have power outages. The problem is big, which can cause short circuits in wires, causing fires or electric shocks. The maturity of laser technology is not only reflected in the surrounding objects and tools.
