Back To Basics - Laser
The word laser is an acronym (an abbreviation pronounced as an ordinary word) of Light Amplification by Stimulated Emission of Radiation. Lasers are devices that produce or amplify a beam of narrow, low-divergence light with a well-defined wavelength within the optical region of the electromagnetic spectrum, covering the infrared, the visible and the ultraviolet.
Lasers have a variety of uses in such areas as surgery, welding and metal cutting, and sound and video recording and reproduction.
Historically, the laser is very different from other 20th century inventions as it first appeared as an imaginary literary creation.
Even before the invention of the first laser in 1960, and when only a handful of specialists were aware of Einstein's prediction of stimulated emission (1917), the term “laser” was already well-known. In particular, numerous science-fiction writers had imagined an extremely powerful beam, capable of destroying anything in its path. These devices were generally controlled by aggressive intergalactic beings bent on wreaking havoc on the world.
Since the discovery of the first real laser in 1961, many others have been developed each year. Current research is focused on the development of solid state lasers (diode lasers, crystal or amorphous solids doped with active ions, optic fibre lasers) with the aim of obtaining much shorter pulses (the present limit is 4.5 fs or 4.5 10-15 seconds) and much greater power (emissions of about 10 kilowatts are now common).
Some important dates:
1961: Javan, Bennet and Herriot build the first gas helium-neon laser operating
continuously at 1.15. In fact, this laser can emit over a whole range of discrete wavelengths, from green to infrared via orange and red (633 nm).
1962: First red helium-neon laser.
1965: First semiconductor lasers.
1966: First coloured pulsed lasers (red, orange, yellow).
1970: First coloured continuous-wave lasers (red, orange, yellow).

Back To Basics - Fiber Optic
Fiber Optic is a glass or plastic fiber that carries light along its length. Fiber optics is the overlap of applied science and engineering concerned with the design and application of optical fibers. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communications. Fibers are used instead of metal wires because signals travel along them with less loss, and they are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so they can be used to carry images, thus allowing viewing in tight spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers.
Light is kept in the core of the optical fiber by total internal reflection. This causes the fiber to act as a waveguide. Fibers which support many propagation paths or transverse modes are called multi-mode fibers (MMF), while those which can only support a single mode are called single-mode fibers (SMF). Multi-mode fibers generally have a larger core diameter, and are used for short-distance communication links and for applications where high power must be transmitted. Single-mode fibers are used for most communication links longer than 550 meters.
Joining lengths of optical fiber is more complex than joining electrical wire or cable. The ends of the fibers must be carefully cleaved, and then spliced together either mechanically or by fusing them together with an electric arc. Special connectors are used to make removable connections.
