laserkäsittely

Laserkäsittely, or laser processing, refers to the use of laser radiation to modify, repair, or remove material or tissue. It covers medical and cosmetic procedures as well as industrial fabrication and scientific applications. The technique relies on directed light energy delivered by a laser, with characteristics such as wavelength, pulse duration, and energy determining how the target absorbs energy and responds.

In medical and dental contexts, lasers may cut, cauterize, or ablate tissue with high precision, minimize bleeding, and spare surrounding tissue. Common applications include refractive eye surgery, dermatological treatments (such as lesions, scars, hair removal), dental therapeutics, and tattoo or pigment removal.

Industrial and materials processing use lasers for cutting, welding, marking, engraving, drilling, surface hardening, and cleaning. Laser cleaning removes oxides and contaminants from metal or stone surfaces without abrasive contact.

Advantages include high precision, non-contact operation, rapid processing, and the ability to work on complex geometries. Limitations include equipment cost, training requirements, safety risks to eyes and skin, and sensitivity to material properties such as reflectivity and turbidity. Process parameters must be optimized to prevent unwanted thermal damage, charring, or microcracking.

Safety and regulation are essential. Lasers are classified by hazard potential, and workplaces follow standards for laser safety, eye protection, and engineering controls. In clinical settings, laser devices are regulated as medical devices with approvals or CE marking in many regions.

Recent developments focus on ultrafast pulsed lasers, fiber and disk laser architectures, and combined modalities to improve precision, speed, and safety in both medical and industrial applications.
