QUANTUM ENHANCEMENT OF A 4 KM LASER INTERFEROME...

The work in this thesis was a part of the experiment of squeezed light injection into the LIGO
interferometer. The work first discusses the detailed design of the squeezed light source which
would be used for the experiment. The specific design is the doubly-resonant  traveling-wave
bow-tie cavity squeezed light source with a new modified coherent sideband locking technique.
The thesis describes the properties affecting the squeezing magnitudes and offers solutions
which improve the gain. The first part also includes the detailed modeling of the
back-scattering noise of a traveling Optical Parametric Oscillator (OPO). In the second part 
the thesis discusses the LIGO Squeezed Light Injection Experiment  undertaken to test squeezed
light injection into a 4km interferometric gravitational wave detector. The results show the
first ever measurement of squeezing enhancement in a full-scale suspended gravitational wave
interferometer with Fabry-Perot arms. Further  it showed that the presence of a squeezed-light
source added no additional noise in the low frequency band. The result was the best sensitivity
achieved by any gravitational wave detector. The thesis is very well organized with the
adequate theoretical background including basics of Quantum Optics  Quantum noise pertaining to
gravitational wave detectors in various configurations  along with extensive referencing
necessary for the experimental set-up. For any non-experimental scientist  this introduction is
a very useful and enjoyable reading. The author is the winner of the 2013 GWIC Theses Prize.
