When cutting glass with CO2 laser, the optimal thickness of the glass substrate is 0.0012-0.0236 inches. If special methods are not used,
Or, in some cases, it is difficult to cut thicker soda lime (float) glass with a laser at one time without using special methods.
In addition to conventional glass, the colored glass samples shown in the photos are all cut with sealed CO2 lasers. As with standard float glass,
straight cuts in stained glass are easy and can be achieved by scoring and breaking. The difficulty is cutting irregular shapes.
The traditional method is to drill holes bit by bit along the edge of the irregular shape to form a curved shape, and then grind it with a diamond grinding wheel,
or use a diamond blade Sawing, but these methods are time-consuming and laborious.

Korea Esseltech claims that it has developed LCD laser glass cutting equipment for the first time in the world. This product abandons the current mechanical cutting method using diamond grinding wheels when cutting Panels in the TFT
LCD production process, and newly developed a non-contact cutting method using laser zero-loss
cutting Cutting method.
This equipment is a laser cutting equipment that can achieve high-speed and clean cutting of LCD, PDP, OLED and other FPD glass through non-contact method.
Laser engraving successfully formed multi-color patterns in colorless transparent glass

Shanghai Light On the basis of pioneering innovative research on laser-induced spatially selective three-dimensional microstructures, the International Collaborating Laboratory of "Photonic Technology" of the Institute of Mechanical and Electrical Engineering selected specially doped colorless transparent glass as the matrix, and used pulse laser induction method to create in the glass according to the design requirements. Successfully carved three-dimensional multi-color patterns inside. Currently, the popular glass laser engraving on the market is actually a pattern formed by focusing on bursting points, so it cannot be colored. This experiment successfully laid a key technical foundation for the technological transformation from colorless interior engraving to full-color interior engraving.
The above-mentioned technological developments of the laboratory were developed on the basis of original basic research. The research group, led by Dr. Qiu Jianrong, the person in charge of the Hundred Talents Program of the Chinese Academy of Sciences and the person in charge of the National Outstanding Youth Fund, has selected the research frontier of laser-induced three-dimensional optical functional microstructure materials and carried out systematic and in-depth exploration in the past two years. Research has resulted in a number of original results. In addition to being published in authoritative international journals, the results have also been featured in magazines such as Nature, Chem.
Eng.
News and other magazines. It has been reported in detail by many domestic and foreign media (such as Xinhuanet, Science and Technology China, German Chemistry Network, Canadian Discovery
Channel, British Materials Today and French L`
Expansion, etc.). Original technology in this area has applied for 4 Chinese invention patents.
The purpose of original innovation is application. One of the most direct practical applications of the above-mentioned innovative technology is the internal engraving of colorful patterns. The laboratory has done a lot of research on the optimization of glass substrates and the optimization of laser and subsequent processing process parameters, achieving color selection and chromaticity control of coloring patterns. At present, patterns of several colors can be carved into a piece of specially doped colorless transparent glass. The researchers' ultimate goal is to engrave full-color patterns within the laser and reduce costs. To this end, they are continuing to work hard.
The formation of colorful internal engravings results from changes in the microstructure of the material in the laser action area. When the linearity of this microstructure reaches the microscale required for optoelectronic integration, functional components with various optoelectronic functions that can be three-dimensionally integrated can be formed, thereby advancing its application into the fields of microelectronics and microphotonics. This is another application goal pursued by researchers.
