Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates .
An Nd:YAG laser drills a hole through a block of nitrile. The intense burst of infrared radiation ablates the highly absorbing rubber, releasing an eruption of plasma. Laser ablation is greatly affected by the nature of the material and its ability to absorb energy, therefore the wavelength of the ablation laser should have a minimum absorption ...
Ablative armor may have additional properties such as added resistance to heat- or laser-based weaponry; if special ablative armor is destroyed, it loses those additional properties. Unlike other types of armor in-game, ablative armor is quite cheap to purchase (since it is so easily destroyed). [citation needed]
Resurfacing can be ablative, which vaporizes tissue and creates wounds, or non-ablative which keeps the skin intact. Laser resurfacing is usually done with a 2940 nm Er:YAG laser or a 10,600 nm CO 2 laser. Complete resurfacing was first done with a CO 2 laser. Both erbium and CO 2 are used to treat deep rhytides, sun damage and age spots.
Ablative laser therapy is used in advanced colorectal cancers to relieve obstruction and to control bleeding. Laser surgery used in hemorrhoidectomy, and is a relatively popular and non-invasive method of hemorrhoid removal. Laser-assisted liver resections have been done using carbon dioxide and Nd:YAG lasers.
There are some target nuclei for ablative surgery and deep brain stimulation. Those nuclei are the motor thalamus, the globus pallidus, and the subthalamic nucleus. [2] Ablative brain surgery was first introduced by Pierre Flourens (1794–1867), a French physiologist. He removed different parts of the nervous system from animals and observed ...

Numerous studies in animals have demonstrated the safety and efficiency of IRE as a non-thermal ablation modality for pulmonary veins in the context of atrial fibrillation treatment. [101] In 2023, irreversible electroporation is being widely used and evaluated in humans, as cardiac ablation therapy to kill very small areas of heart muscle.
