The carbon-dioxide laser (CO 2 laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964 [1] and is still one of the most useful types of laser. Carbon-dioxide lasers are the highest-power continuous-wave lasers that are currently available.
Fractional laser photothermolysis (FP) is a form of laser-based skin resurfacing, with several devices on the market, such as Fraxel. A fractional laser delivers laser light to the skin. Hundreds or thousands of laser pinpoints may be used per square inch, leaving healthy skin between the ablated areas.
Doctor performs Fraxel laser procedure. Fraxel Laser Treatment is a line of lasers developed by Reliant Technologies in 2004. It was developed from a US patent licensed from the Wellman Center for Photomedicine. R. Rox Anderson was the inventor. Fraxel lasers cause fractional photothermolysis for skin resurfacing.
My honest thoughts on the treatment, plus info on how it works, who it's best for, what to expect during a treatment, the downtime, and if it's worth the cost.
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
Gas dynamic lasers can be pumped by combustion or adiabatic expansion of gas. Any hot and compressed gas with appropriate vibrational structure could be utilized. The explosively pumped gas dynamic laser is a version of GDL pumped by expansion of explosion products. Hexanitrobenzene and/or tetranitromethane with metal powder is the preferred ...
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 .
A TEA laser is a gas laser energized by a high-voltage electrical discharge in a gas mixture generally at or above atmospheric pressure. The most common types are carbon dioxide lasers and excimer lasers , both used extensively in industry and research; less common are nitrogen lasers .
