Laser Technology

Challenges and Breakthroughs

In the field of cutting and marking glass and crystals, which are resistant to visible and near-infrared spectra and have poor thermal stability, laser technology faces significant challenges. Nevertheless, the rapid advancement of science and technology has led to remarkable achievements in this area, especially the outstanding performance of carbon dioxide lasers in glass processing. This article aims to delve into the problems and solutions that may arise in laser processing of glass and crystals, analyze the practical application of various methods, and explore future development trends.

Laser Marking Technology

CO2 lasers exhibit excellent adsorption capabilities on the surfaces of glass products, allowing for excellent processing results and ensuring the presentation of high-quality markings. This technology meets the identification and tracking needs of industrial production and is widely used in the production of art and handicrafts, bringing unique aesthetic value to glass products.

Optical Breakthrough and Cutting

In addition to marking technology, the high-energy beam penetration method has become one of the unique and important tools in the glass manufacturing industry, using high-energy density lasers for precision processing. In this process, the high-intensity laser first draws lines on the surface of the glass, and then completes the cutting and fracturing operations through precision instruments, finally separating them. Although this process has obvious advantages in certain fields, there is still room for improvement in contour cutting quality, necessitating further research and continuous improvement.

Thermal Separation and Pure Laser Ablation

In addition, the combination of new thermal separation techniques and pure laser ablation methods has been extensively studied and widely applied in practical areas. For the high-precision cutting demands in specific scenarios, the strategy of using laser thermal separation and pure laser ablation complements each other to achieve fine processing of glass and crystal materials. For example, in the production process of smartphone displays, laser thermal separation mainly performs linear cutting tasks, while high-power ultrafast lasers are responsible for the erosion of curved parts.

Ultrafast Laser Drilling

In practical applications, ultra-high-speed laser drilling technology has been widely used in the manufacturing processes of glass and other transparent materials. By combining ultrafast laser systems with five-axis drilling equipment, it is possible to accurately process vertical hole walls and ensure that light can penetrate inside transparent materials, especially suitable for the preparation of high-precision holes.

Laser Filamentation Technology

In recent years, the rapid progress in laser technology has made laser filamentation technology a forefront topic in the precise processing of glass. This process uses high-speed lasers to induce significant three-dimensional microscale deformation in highly transparent materials, also known as “laser filamentation.” Based on the Kerr effect and the self-focusing characteristics of optical mechanisms, stable filament-shaped structures are formed inside such materials, achieving almost perfect seamless cutting or drilling effects. This undoubtedly greatly expands the practical application range of glass precision processing.

Application Prospects and Outlook

With the leaps in laser technology and its vast application prospects, laser processing of glass and crystals demonstrates tremendous potential. This technology spans various industries, from industrial manufacturing to art design, electronic devices to medical equipment. Looking ahead, innovative processes and technologies centered on laser technology will gradually permeate the field of glass and crystal processing, injecting endless possibilities into the prosperity and progress of human society.
