Recognition for Maiman and his laser invention continued posthumously. In a 2007 obituary testimonial, maser co-inventor Charles H. Townes described Maiman's 1960 Nature article on his laser as "probably more important per word than any of the papers published by Nature over the past century."
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]
(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.
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.
In honor of AOL's 35th birthday on May 24, we're taking a look back at some of the company's definitive moments, like history-breaking mergers and record-breaking numbers, and how it shaped the ...
"World's First Laser: May 16, 1960, Malibu, California, by Theodore H. Maiman" The first working laser was created by U.S. physicist Theodore Maiman, who focused a high-powered flash lamp on a silver-coated ruby rod at the Hughes Research Laboratory in Malibu, California. [58]
