Laserpurkaus

Laserpurkaus is a phenomenon where a laser beam interacts with a material, leading to the removal or modification of that material. This process typically involves focusing a high-intensity laser beam onto a specific spot on the material's surface. The intense energy absorbed by the material causes it to heat up rapidly, melt, vaporize, or even undergo plasma formation. The ejected material then forms a plume that is cleared away, either by the pressure of the laser-induced plasma or by an assisting gas flow.

The specific outcome of laserpurkaus depends on several factors, including the laser's wavelength, pulse duration, energy, and the material's properties such as its absorption coefficient, thermal conductivity, and melting point. Short-pulsed lasers, such as nanosecond or femtosecond lasers, are often used for precise material removal with minimal heat-affected zones. This makes them suitable for applications requiring high accuracy and delicate processing.

Laserpurkaus finds widespread use in various industrial and scientific fields. In manufacturing, it is employed for cutting, drilling, marking, and engraving a wide range of materials, including metals, plastics, ceramics, and composites. In research, it is used for techniques like laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) for elemental analysis and in the fabrication of micro- and nanostructures. The ability to achieve high precision and contactless processing makes laserpurkaus a valuable tool for advanced manufacturing and scientific exploration.
