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]
H - Trigger wire. 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 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 ...
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]

If your employee came to you in 1975 and told you he'd invented the digital camera, what would you do? If you were Kodak, the answer was to effectively shove him in a closet and hope the product ...
American engineer Theodore Maiman develops the first laser: 1962: Nick Holonyak invented the LED. 1963: First home Videocassette recorder (VCR) 1963: Electronic calculator: 1966: Fiber-optic communication by Kao and Hockham 2008: American scientist R. Stanley Williams invented the memristor which was proposed by Leon O. Chua in 1971.
Few objects in the world are more immediately recognizable than the barcode—more than 6 billion are scanned every single day. Here’s what to know about their history.
