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]
A ruby laser is a solid-state laser that uses a synthetic ruby crystal as its gain medium. 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.
The word laser originated as an acronym for light amplification by stimulated emission of radiation. [1] [2] The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow and the optical amplifier patented by Gordon Gould. [3] [4] [5]
(Credit for the invention of the laser is disputed, since Charles Townes and Arthur Schawlow were the first to publish the theory and Theodore Maiman was the first to build a working laser). Gould is best known for his thirty-year fight with the United States Patent and Trademark Office to obtain patents for the laser and related technologies.
The first laser, invented by Theodore Maiman in May 1960. Nd:YAG laser: 1.064 μm, (1.32 μm) Flashlamp, laser diode: Material processing, rangefinding, laser target designation, surgery, tattoo removal, hair removal, research, pumping other lasers (combined with frequency doubling to produce a green 532 nm beam). One of the most common high ...
The laser works by the same principle as the maser, but produces higher-frequency coherent radiation at visible wavelengths. The maser was the precursor to the laser, inspiring theoretical work by Townes and Arthur Leonard Schawlow that led to the invention of the laser in 1960 by Theodore Maiman. When the coherent optical oscillator was first ...
Japanese engineer Jun-ichi Nishizawa invented the avalanche photodiode [20] 1953: First fully transistorized computer in the U.S. 1958: American engineer Jack Kilby invented the integrated circuit (IC). 1960: American engineer Theodore Maiman develops the first laser: 1962: Nick Holonyak invented the LED. 1963: First home Videocassette recorder ...
The laser was invented in 1960 by Theodore Maiman, [3] and its potential uses in medicine were subsequently explored. Lasers benefit from three interesting characteristics: directivity (multiple directional functions), impulse (possibility of operating in very short pulses), and monochromaticity.
