16 Facts About Laser ablation

Usually, laser ablation refers to removing material with a pulsed laser, but it is possible to ablate material with a continuous wave laser beam if the laser intensity is high enough.

Simplest application of laser ablation is to remove material from a solid surface in a controlled fashion.

Laser ablation cleaning is used for efficient rust removal from iron objects; oil or grease removal from various surfaces; restoration of paintings, sculptures, frescoes.

Laser ablation is one of preferred techniques for rubber mold cleaning due to minimal surface damage to the mold.

Variation of this type of application is to use laser ablation to create coatings by ablating the coating material from a source and letting it deposit on the surface to be coated; this is a special type of physical vapor deposition called pulsed laser deposition, and can create coatings from materials that cannot readily be evaporated any other way.

Remote laser spectroscopy uses laser ablation to create a plasma from the surface material; the composition of the surface can be determined by analyzing the wavelengths of light emitted by the plasma.

Laser ablation is used to create pattern, removing selectively coating from dichroic filter.

Finally, laser ablation can be used to transfer momentum to a surface, since the ablated material applies a pulse of high pressure to the surface underneath it as it expands.

Laser ablation in the liquid phase is an efficient method to exfoliate bulk materials into their 2-dimensional forms, such as black phosphorus.

Laser ablation is used as a sampling method for elemental and isotopic analysis, and replaces traditional laborious procedures generally required for digesting solid samples in acid solutions.

Laser ablation sampling is detected by monitoring the photons emitted at the sample surface - a technology referred to as LIBS and LAMIS (Laser Ablation Molecular Isotopic Spectrometry), or by transporting the ablated mass particles to a secondary excitation source, like the inductively coupled plasma.

Laser ablation is used in science to destroy nerves and other tissues to study their function.

Laser ablation can be used to destroy individual cells during embryogenesis of an organism, like Platynereis dumerilii, to study the effect of missing cells during development.

Laser ablation is used in a variety of medical specialties including ophthalmology, general surgery, neurosurgery, ENT, dentistry, oral and maxillofacial surgery, and veterinary.

Some of the most common procedures where laser ablation is used include LASIK, skin resurfacing, cavity preparation, biopsies, and tumor and lesion removal.

Laser ablation can be used on benign and malignant lesions in various organs, which is called laser-induced interstitial thermotherapy.
