Informationen über Laser Processes Introduction

During the laser engraving process, the target material is essentially vaporized by the laser beam. To achieve this result, the intensity of the laser beam is set to exceed a specific threshold value. This threshold intensity is particularly high with materials that are electrically conductive, such as metals. The result is often a cone-shaped indentation influenced by the laser beam profile and the heat conductivity of the target material. The laser engraving technique is typically the fastest way of processing material. With laser cutting, a plate-type material is separated by a focussed laser beam. Basically, there is a choice between laser beam fusion cutting and laser beam sublimation cutting. With laser beam fusion cutting the material, e.g. acrylic, is melted or vaporised. With sublimation cutting, the material, e.g. wood, is vaporised by missing out the liquid phase.
