Abstract
THE discovery of Laser1 in 1960 is considered to
be one of the most important scientific achievements
of recent years. Laser is a unique
device for generating and amplifying a beam of
light (or any other electro-magnetic radiation)
having one particular wavelength, the waves of
which are all in step (coherent). The name
LASER is a shortened form to denote Light
Amplification by Stimulated Emission of Radiation.
Although the physical principles upon
which a laser is based have been known since
the 1930s, the conception that such a device
could be made possible did not occur until the
development of masers in the early 1950. The
famous paper by Schawlow and Townes2 in
1958 suggested the possibility of such a device
to generate intense coherent light beam. The
suggestion of Townes proved to be of great
scientific value which resulted in the award of
the Nobel Prize to him in Physics in 1964.
