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 ...
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 ...
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 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.
In the fifth century BCE, Empedocles postulated that everything was composed of four elements; fire, air, earth and water. He believed that Aphrodite made the human eye out of the four elements and that she lit the fire in the eye which shone out from the eye making sight possible. If this were true, then one could see during the night just as ...
Based on this observation, and the fact that the inter-facial angles in each crystal species always have the same value, Haüy concluded that crystals must be periodic and composed of regularly arranged rows of tiny polyhedra (molécules intégrantes). This theory explained why all crystal planes are related by small rational numbers (the law ...

The first page of the notebook in which Gould coined the acronym LASER and described the essential elements for constructing one. Gould recorded his analysis and suggested applications in a laboratory notebook under the heading "Some rough calculations on the feasibility of a LASER: Light Amplification by Stimulated Emission of Radiation"—the ...
