Theodore Harold Maiman (July 11, 1927 – May 5, 2007) was an American engineer and physicist who is widely credited with the invention of the laser. [1] [2] [3] [4 ...
For example, the first working laser was a ruby laser, made from ruby (chromium-doped corundum). The population inversion is maintained in the dopant. These materials are pumped optically using a shorter wavelength than the lasing wavelength, often from a flash tube or another laser.
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 ...
The laser printer was invented at Xerox PARC in the 1970s. Laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, quality and speed have increased as prices have decreased, and the once cutting-edge printing devices are now ubiquitous.
Gary Keith Starkweather (January 9, 1938 – December 26, 2019) [1] was an American engineer who invented the laser printer and color management.. Starkweather received a B.S. in physics from Michigan State University in 1960 and an M.S. in optics from the University of Rochester in 1966.

The first commercial implementation of a laser printer was the IBM model 3800 in 1976, used for high-volume printing of documents such as invoices and mailing labels. It is often cited as "taking up a whole room," implying that it was a primitive version of the later familiar device used with a personal computer .
