In addition to his patent for the first working laser, Maiman authored a number of patents on masers, lasers, laser displays, optical scanning, and modulation. [ 34 ] Prior to his death, Maiman held an adjunct professor position in the School of Engineering Science at Simon Fraser University , where he worked on the development of curricula in ...
The first working laser was a ruby laser made by Theodore H. "Ted" Maiman at Hughes Research Laboratories on May 16, 1960. [ 1 ] [ 2 ] Ruby lasers produce pulses of coherent visible light at a wavelength of 694.3 nm , which is a deep red color.
Even though Gould had signed away eighty percent of the proceeds to finance his court costs, he made several million dollars. [34] "I thought that he legitimately had a right to the notion to making a laser amplifier", said William R. Bennett, who was a member of the team that built the first laser that could fire continuously. "He was able to ...
In 1997, Yamagata held an exhibition, Element-A Laser Installation, at Fred Hoffman Fine Art Gallery. He showed a work from "Earthly Paradise" incorporated with laser for the décor of the Academy Awards Governor's Ball at the Oscars. In 1998, he had an exhibition of laser installation, Sculpture of Light, at the First St. Bridge in Los Angeles ...
1960 Theodore H. Maiman creates the first laser. 1962 Nick Holonyak Jr. develops the first practical visible-spectrum (red) light-emitting diode. 1963 Kurt Schmidt invents the first high pressure sodium-vapor lamp. [18] 1972 M. George Craford invents the first yellow light-emitting diode.
At the same time, development of short and ultrashort laser pulses—created by Q-switching and mode-locking techniques—opened the way to the study of unimaginably fast ("ultrafast") processes. Applications for solid state research (e.g. Raman spectroscopy) were found, and mechanical forces of light on matter were studied.

A 50 W FASOR, based on a Nd:YAG laser, used at the Starfire Optical Range. Solid-state lasers use a crystalline or glass rod that is "doped" with ions that provide the required energy states. For example, the first working laser was a ruby laser, made from ruby (chromium-doped corundum). The population inversion is maintained in the dopant ...
