欧州最早使用的激光器——佩特二氧化硫激光器,是1966年。当时用以研究航空工业难以切割的新型材料的焊接与切割。后来发展了折叠式CO_2激光器。这种结构的激光器至今仍然在激光器制造厂中采用。这些原始的激光器引起了如“费兰提”这类公司的极大兴趣。因为激光能切割种类繁多的薄型钢材而不变形,其优越性能与瓦斯气体切割系统形成鲜明对照。此外,激光器还可以用来切割塑料、木材、橡胶、石棉等材料。功率500W的CO_2激光器能以1米/分左右的速度切割4～5mm厚的钢材。早期CO_2激光器的应用,不但提供了激光切割、焊接和热处
The earliest laser used in Europe, the Patel Sulfur Dioxide Laser, was 1966. It was then used to study the welding and cutting of new materials that are difficult to cut by the aerospace industry. Later developed a folded CO_2 laser. Lasers of this type are still used today in laser manufacturing plants. These original lasers have drawn great interest from companies like Ferretti. Because the laser can cut a wide variety of thin steel without deformation, its superior performance and gas gas cutting system in stark contrast. In addition, the laser can also be used to cut plastic, wood, rubber, asbestos and other materials. The CO 2 laser with power of 500W can cut 4 ~ 5mm thick steel at the speed of 1m / min. Early CO 2 laser applications, not only provides laser cutting, welding and heat treatment
