Isolation of LIGO
Gravitational waves can help in detection various astrophysical events
occurring in our universe. This can also pave a path to validate
theories built around the existence of gravitational waves. However, the
detection of these waves is an arduous task owing to the extraordinary
small strain experienced by the earth due to gravitational waves.
Various methods have been proposed for their detection, out of which
laser interferometers are the most popular ones. Laser interferometers
offers large projection range and high displacement sensitivity. Among
the existing detector, Laser interferometer gravitation-wave observatory
(LIGO) is the most sensitive operational detector. LIGO consists of two
longs arms, referred as beam tubes, that are placed orthogonal to each
other. The arms of the LIGO accommodates a Michleson interferometer with
a cavity (Fabry-Perot). The mirrors at the extremity of the cavity serve

The mirrors at the extremity of the cavity serve
as inertial test masses which responds to the strain induced due to the
gravitational waves. The optics of the LIGO are suspended like a
pendulum. The schematics of the LIGO are shown in
