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.

Long, thin, pliable carpet is laid on the ?oor. One end of the carpet is bent back and then pulled backwards with constant unit velocity, just above the part of the carpet which is
(i) Electric field lines come out of positive charge and go into the negative charge. (ii) Tangent to the field line at any point gives the direction of the field at that point.
