2. Carbon-dioxide laser - Wikipedia

   en.wikipedia.org/wiki/Carbon-dioxide_laser

   The carbon-dioxide laser ( CO2 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. They are also quite efficient: the ratio of output ...

3. TEA laser - Wikipedia

   en.wikipedia.org/wiki/TEA_laser

   TEA laser. 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 ...

   Carbon dioxide laser. 10.6 μm, (9.4 μm) Transverse (high-power) or longitudinal (low-power) electrical discharge. Material processing ( laser cutting, laser beam welding, etc.), surgery, dental laser, military lasers . Carbon monoxide laser. 2.6 to 4 μm, 4.8 to 8.3 μm.

5. C. Kumar N. Patel - Wikipedia

   en.wikipedia.org/wiki/C._Kumar_N._Patel

   C. Kumar N. Patel. 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. Because the atmosphere is quite transparent to infrared light, CO 2 lasers are also used ...

6. Laser - Wikipedia

   en.wikipedia.org/wiki/Laser

   The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of radiation. [1] [2] The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow.

7. Laser beam welding - Wikipedia

   en.wikipedia.org/wiki/Laser_beam_welding

   Laser beam welding ( LBW) is a welding technique used to join pieces of metal or thermoplastics through the use of a laser. The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates. The process is frequently used in high volume and precision requiring applications using automation, as in the ...
