Laserablatiivinen

Laserablatiivinen refers to a process where a laser beam is used to remove material from a surface. The word comes from "ablation," which means the wearing away or removal of material. In laser ablation, a high-energy laser pulse is focused onto a material, causing it to rapidly heat up, vaporize, and turn into a plasma. This plasma then expands and is carried away from the surface. The process is very precise and can remove extremely small amounts of material with high accuracy.

This technique has a wide range of applications across various fields. In manufacturing and industry, laser ablation is used for micro-machining, engraving, drilling, and creating intricate patterns on materials like metals, plastics, and ceramics. It is particularly useful for delicate or heat-sensitive materials where traditional machining methods might cause damage. In scientific research, laser ablation is employed for sample preparation in techniques like mass spectrometry and for creating nanostructures. It is also utilized in the medical field, for example, in eye surgery to reshape the cornea or for removing skin lesions.

The effectiveness and precision of laser ablation depend on several factors, including the laser's wavelength, pulse duration, power, and the material's properties. Different types of lasers, such as excimer lasers or femtosecond lasers, are chosen based on the specific application and the desired outcome. The non-contact nature of laser ablation makes it a clean and efficient method, often requiring minimal post-processing.
