'C. Kumar N. Patel' developed the
carbon dioxide laser in 1963
[1]; it is now widely used in industry for cutting and
welding, as a
laser scalpel in
surgery, and in
laser skin resurfacing. Because the
atmosphere is quite transparent to infrared light, CO
2 lasers are also used for military
rangefinding using
LIDAR techniques.
Patel was born in
Baramati,
India on
1938-07-02. He received a
Bachelor of Engineering (B.E.) degree from the College of Engineering in
Poona, India and the M.S. and Ph.D. 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.
Patel was later appointed as Vice Chancellor for Research at the
University of California, Los Angeles, where he is also Professor of Physics.

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."
[2] Patel currently holds 36 U.S.
patents relating to lasers and
laser applications. In addition to the carbon dioxide laser, he also developed the "spin-flip" infrared
Raman laser.
