Scientific principle behind a laser:
The basic scientific principle behind a laser was first put forward by Dr. Charles H.
Towns in 1954 which later led to the development of the laser first developed laser introduced in the year of 1960.
Laser is simply a source of light, but the light has extra - ordinary properties. Laser light is distinguished from an ordinary light source by its
(1) Coherence
(2) Directionality
(3) Monochromaticity and
(4) High intensity.
Lack of coherence makes ordinary light an optical noise. The process of achieving 'population inversion' is called PUMPING. Laser is an extra - ordinary light emitted under stimulated and amplified conditions so that the beam is characterized by high intensity, specific directionality, high monochromaticity and high degree of coherence.
