Carbon-dioxide lasers have become useful in surgical procedures because water (which makes up most biological tissue) absorbs this frequency of light very well. Some examples of medical uses are laser surgery and skin resurfacing ("laser facelifts ", which essentially consist of vaporizing the skin to promote collagen formation). [ 9 ]
Q-switching, sometimes known as giant pulse formation or Q-spoiling, [1] is a technique by which a laser can be made to produce a pulsed output beam. The technique allows the production of light pulses with extremely high peak power, much higher than would be produced by the same laser if it were operating in a continuous wave (constant output) mode.
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. The acronym "TEA" stands for "transversely excited atmospheric".
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).
It can be combined with liposuction to help tighten and smooth over the new contours after removal of excess fat. 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.
Chandra Kumar Naranbhai Patel (born 2 July 1938) is an electrical engineer.He developed the carbon dioxide laser in 1963; [1] it is now widely used in industry for cutting and engraving a wide range of materials like plastic and wood.
Most recently, Real Housewives of Orange County star Tamra Judge underwent a brow lift in addition to having a CO2 laser and a blue chemical peel done. She took her followers along for the ride ...
The laser chosen for the Skif spacecraft was a 1-megawatt carbon dioxide laser, developed for the Beriev A-60 aircraft (an Il-76 flying laboratory with a combat laser). The introduction of the Energia, capable of launching about 95 tonnes into orbit, finally allowed the spacecraft to accommodate the massive laser. The massive exhaust of the ...
