Hall developed the first semiconductor laser diode in 1962, while working at General Electric in Schenectady, New York. [4] In the 1970s, Hall's work focused on photovoltaics and solar cells. He retired in 1987, having been granted 43 U.S. patents during his career.
Nick Holonyak Jr. (/ h ʌ l ɒ n j æ k / huh-LON-yak; November 3, 1928 – September 18, 2022) was an American engineer and educator.He is noted particularly for his 1962 invention and first demonstration of a semiconductor laser diode that emitted visible light.
A laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction.
Celebrating 50 years since the advent of LED technology, Nick Holonyak compares his first visible LED invention to GE Lighting's latest 27-watt LED available in 2013, replacing the 100-watt ...
Basov with co-workers proposed Disk laser in 1966 [8] and realized experimentally the thin disk active mirror semiconductor lasers. [9] He developed with colleaguaes the first nonlinear theory of coherent addition of laser sets. [10] N.G.Basov encouraged the researchers in nonlinear optics in Lebedev Institute who discovered the optical phase ...
Today, however, semiconductor laser scientists agree that the key design concept that enabled the room-temperature diode laser, namely the double-heterostructure design, was invented in the Soviet Union in 1964 by Rudolf F. Kazarinov and Zhores Alferov, as recorded in a Russian patent application filed that year.
In 1953 Boyle joined Bell Labs where he invented the first continuously operating ruby laser with Don Nelson in 1962, [6] and was named on the first patent for a semiconductor injection laser. [6] He was made director of Space Science and Exploratory Studies at the Bell Labs subsidiary Bellcomm in 1962, providing support for the Apollo space ...
Maiman was granted a patent for his invention, [12] and he received many awards and honors for his work. His experiences in developing the first laser and subsequent related events are recounted in his book, The Laser Odyssey, [13] later being republished in 2018 under a new title, The Laser Inventor: Memoirs of Theodore H. Maiman. [14]
