薄片状金属，特别是低磷钢和不锈钢板，一直是功率不超过2kw的激光切割的主要对象。然而随着功率高达3kw具有高质量光模式的激光器上市，现在厚度达15mm的中厚度金属激光切割得到了飞速发展．就钢而言，厚度超过10mm时称为厚材料，与薄材料切割相比，这类材料的切割具有不同的 Flake-like metals, especially low phosphorus and stainless steel, have been the main targets of laser cutting with powers no more than 2kW. However with the launch of high-power optical mode lasers with powers up to 3kW, medium-thickness metal laser cutting up to 15mm in thickness has been rapidly developed. In the case of steel, when thicker than 10 mm, it is called a thick material, and cutting of such material has a different
