Who invented Lazor and fiber optics?

Answer 1

Fiber Optics:

Much like a watch, which has no inventor per se, fiber optics was an evolving technology dating back to proof of concept in 1854 by John Tyndall who proved that light could be "bent" to follow a path.

In 1880, Alexander Graham Bell invented his 'Photophone', which transmitted a voice signal on a beam of light.

In 1888, the medical team of Roth and Reuss of Vienna used bent glass rods to illuminate body cavities.

... as you can see, the idea of bending light or using light to transmit has been around for a very long time.

Corning Glass researchers Robert Maurer, Donald Keck and Peter Schultz invented fiber optic wire or "Optical Waveguide Fibers" (patent #3,711,262) capable of carrying 65,000 times more information than copper wire, through which information carried by a pattern of light waves could be decoded at a destination even a thousand miles away.

The laser was actually an offshoot of the MASER (a microwave emitter instead of a light emitter), invented by Charles Townes.

There were two patent applications for the laser, one filed by Townes, and the other by Bell Labs in 1959. The patent battle lasted for nearly 30 years.
