C. Kumar N. Patel

In 2018 C. Kumar N. Patel became an Honorary Member of the American Laser Study Club which a year later named an award in his honor.

In 1996, President Bill Clinton awarded Patel the National Medal of Science, "[f]or his fundamental contributions to quantum electronics and invention of the carbon dioxide laser, which have had significant impact on industrial, scientific, medical, and defense applications." In addition to the carbon dioxide laser, he also developed the "spin-flip" infrared Raman laser.

From 1993–1999, Patel served as vice chancellor for research at the University of California, Los Angeles, where he is also professor of physics and adjunct professor of electrical engineering.

Patel was born in Baramati, India, and received a Bachelor of Engineering (B.E.) degree from the Government College of Engineering, the University of Pune, India and the M.S. and PhD in electrical engineering from Stanford University in 1959 and 1961, respectively. Patel joined Bell Laboratories in 1961, and subsequently became Executive Director of the Research, Materials Science, Engineering and Academic Affairs Division at AT&T Bell Laboratories in Murray Hill, New Jersey, where he developed the carbon dioxide laser. Patel's discovery, in 1963, of the laser action on the vibrational-rotational transitions of carbon dioxide and his discovery, in 1964, of efficient vibrational energy transfer between molecules, led to a series of experiments which demonstrated that the carbon dioxide laser was capable of very high continuous-wave and pulsed power output at very high conversion efficiencies.

Chandra Kumar Naranbhai Patel (born 2 July 1938) is an electrical engineer. He developed the carbon dioxide laser in 1963; 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, CO2 lasers are also used for military rangefinding using LIDAR techniques.
