Carbon dioxide (COâ‚‚) lasers are among the earliest developed high-power continuous lasers, with well-established commercial applications. These lasers have found widespread use in material processing, medical treatments, military equipment, and environmental monitoring. Their early development and application can be traced back to the late 1970s when COâ‚‚ lasers were imported from abroad for industrial and medical purposes. By the late 1980s, they had become more commonly used in material processing, marking a significant shift in manufacturing technology.
Despite their growing popularity, the adoption of COâ‚‚ laser systems has not been without challenges. As a relatively new tool compared to traditional methods, laser processing technology brings unique difficulties, especially in integration and operation. This paper explores the current status and evolution of COâ‚‚ lasers across different fields, highlighting common issues users face. It also categorizes the applications based on laser power levels, providing insights into the challenges encountered in practical use.
One of the key advantages of COâ‚‚ lasers is their high power output and energy conversion efficiency. Typical closed COâ‚‚ lasers can produce several tens of watts continuously, while lateral flow models can reach hundreds of kilowatts. Additionally, these lasers operate at wavelengths around 10 micrometers, which aligns with the atmospheric transmission window, making them ideal for long-range applications. Their output beams also exhibit excellent optical quality, coherence, and stability, enabling diverse uses such as cutting, welding, and medical procedures.
Looking ahead, COâ‚‚ lasers are expected to evolve in several directions. High-power cross-flow models are being developed for advanced material processing and heat treatment. Acousto-optic Q-switched COâ‚‚ lasers are designed for applications like ranging, environmental sensing, and space communication. Compact RF-excited waveguide COâ‚‚ lasers aim to improve portability and longevity for industrial and military use. Portable TEA (Transversely Excited Atmospheric) COâ‚‚ lasers offer flexibility for field operations, while high-power continuous COâ‚‚ lasers are being optimized for precision cladding and repair tasks.
In China, efforts have focused on adapting and improving both axial and cross-flow COâ‚‚ lasers. While cross-flow models are cost-effective and powerful, they suffer from lower beam quality, limiting their use to remanufacturing and surface treatments. In contrast, German axial COâ‚‚ lasers provide superior beam quality but come with higher costs and complexity, making them less accessible for small and medium enterprises. As a result, axial COâ‚‚ lasers are not seen as the primary direction for future development in China.
Overall, COâ‚‚ lasers continue to play a crucial role in modern technology, with ongoing innovations aimed at enhancing performance, reliability, and accessibility.
The armatures can be classified into several categories. Firstly, there are electromagnetic armatures, which operate based on the interaction of magnetic fields. Then, there are mechanical armatures, often used in mechanical systems for transmitting motion. Permanent magnet armatures are another type, relying on the properties of permanent magnets. Hybrid armatures combine different principles for enhanced performance. Additionally, some armatures are designed specifically for high-speed applications, while others are for heavy-duty tasks.
