Gordon Gould

Optically Pumped Laser Amplifiers

U.S. Patent Nos. 4,053,845; 4,704,583
Inducted in 1991
Born July 17, 1920 - Died Sept. 16, 2005

Gordon Gould coined the word laser and patented optically pumped and discharge excited laser amplifiers now used in industrial, commercial, and medical applications of lasers. Born in New York City, Gould's ambition was to be an inventor. After majoring in physics at Union College, he went on to Yale University for graduate work in spectroscopy. He received an M.S. in physics in 1943 and for the rest of World War II worked on the Manhattan Project. After the war, he studied at Columbia University and laid the groundwork for his original concepts of laser technology.

Gould wrote down his first ideas for the laser in a notebook entitled "Some rough calculations on the feasibility of a LASER: Light Amplification by Stimulated Emission of Radiation," the first use of this acronym. However, because he misunderstood an attorney's advice, he didn't file for a patent until 1959, after other laser researchers had already filed. Since Gould's original patent application contained a number of different inventions it was put through a series of five separate interferences by the Patent Office.

Thus, it was not until 1977 that the first of Gould's basic laser patents was issued. These lasers are used in 80 percent of the industrial, commercial, and medical applications of lasers. Gould also holds patents on laser uses and fiber optic communications.
