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 .

Laser ablation synthesis in solution (LASiS) is a commonly used method for obtaining colloidal solution of nanoparticles in a variety of solvents. [ 1 ] [ 2 ] Nanoparticles (NPs,), are useful in chemistry, engineering and biochemistry due to their large surface-to-volume ratio that causes them to have unique physical properties. [ 3 ]
Ablation near the electrode in a flashtube.The high-energy electrical arc slowly erodes the glass, leaving a frosted appearance. Ablation (Latin: ablatio – removal) is the removal or destruction of something from an object by vaporization, chipping, erosive processes, or by other means.
Asteroid laser ablation is a proposed method for deflecting asteroids, involving the use of a laser array to alter the orbit of an asteroid. Laser ablation works by heating up a substance enough to allow gaseous material to eject, either through sublimation (solid to gas) or vaporization (liquid to gas). For most asteroids this process occurs ...
Lasers are used to treat cancer in several different ways. Their high-intensity light can be used to shrink or destroy tumors or precancerous growths. Lasers are most commonly used to treat superficial cancers (cancers on the surface of the body or the lining of internal organs) such as basal-cell skin cancer and the very early stages of some cancers, such as cervical, penile, vaginal, vulvar ...
Laser radiation being delivered via a fiber for photodynamic therapy to treat cancer. A 40-watt CO 2 laser with applications in ENT, gynecology, dermatology, oral surgery, and podiatry. Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, [1] photorejuvenation, and laser surgery.
Laser ablation is not recommended for in vivo, as the potential damage from laser was too high. High cost of operation, and extensive operating time narrowed its accessibility for cell studies. [4] Recently, laser ablation was applied with ICP-MS to develop LA-ICP-MS analysis technique. In which utilizes the precision and ability to change ...
