In textile manufacturing, a laser cutting bridge system is an industrial machine for cutting and engraving textile materials (i.e. fabrics). It is formed by a galvanometric laser head and carbon-dioxide laser (CO 2 laser) source that runs along an horizontal beam (the bridge) supported by two lateral columns and sometimes by central columns.
The CO 2 laser is suited for cutting, boring, and engraving. The neodymium (Nd) and neodymium yttrium-aluminium-garnet lasers are identical in style and differ only in the application. Nd is used for boring and where high energy but low repetition are required. The Nd:YAG laser is used where very high power is needed and for boring and engraving.
