Concluding remarks on LIGO-India
• Home ground advantage. Unique & unprecedented opportunity.
• Threshold of discovery and launch of a new observational window
in human history!! Century after Einstein GR, 40 yrs of Herculean global efforts
• Unlike other projects the key crucial components and subsystems have
already been developed and individually tested & validated and are ready to
be taken up for installation. So there are no uncertainties regarding the
technological feasibility.
• No requirement of a incubation period for technology demonstration,
pathfinder mission etc. as the current design and technology for the detector
is based on R&D and development done by the LSC over the past to decades
• India pays true tribute to fulfilling Chandrasekhar’s legacy:
”Astronomy is the natural home of general relativity”
IUCAA should be a key stake holder
• Attain high technology gains for partnering Indian labs & industries
Thank you !!!

long mode-defining cavity), and suspended mode-matching telescope optics.
• 5 "BSC chamber" seismic isolation systems (two stage, six degree of freedom, active isolation stages
capable of ~200 kg payloads)

Advanced LIGO Laser
• Designed and contributed by Albert Einstein Institute, Germany
• Much higher power (to beat down photon shot noise)
– 10W
 180W (narrow sub kHz line width)
• Better stability
– 10x improvement in intensity (nano ppm) and frequency
stability (mHz)
• Unique globally. Would require years of focused R &D effort in India
• AdvLIGO laser has spurred RRCAT to envisage planning development of
similar laser capability in the next 5 year plans. IIT M/K group also interested.
• Multiple applications of narrow line width laser : Freq time stand, precision
metrology, Quantum key distribution, high sensitivity seismic sensors (geo sc.),
coherence LIDAR (atm sc.), ….
Advanced LIGO Mirrors
•
• Larger size
– 11 kg  40 kg, 2534 cm
• Smaller figure error
– 0.7 nm  0.35 nm
• Lower absorption
– 2 ppm  0.5 ppm
• Lower coating thermal noise
Surface specs (/3000) : 100 x best telescope optics
• Surface specs currently available in India for much
smaller sizes /20

small scale, eg., for TIFR 3m prototype
• Technology for such mirror useful for high optical
metrology and other specialized applications
LIGO-India: unique once-in-a-generation opportunity
“Quantum measurements”
further improvement via squeezed light:
• Potential technology spin-offs will impact quantum computing and
quantum key distribution (QKD) for secure communications.
(IITM approached by ITI for QKD development.)
• New ground for optics and communication technology in India
+ Cold atom labs (IISc., IISERP,….), Precision force measurements,….
• High Potential to draw
the best Indian UG students, typically
interested in theoretical physics, into experimental science !!!

Director RRCAT’s statement
The LIGO-India being a project of National interest and entailing
high end technologies such as lasers, optics and vacuum is of great
interest to RRCAT. RRCAT would provide all the required support for key
technological expertise for lasers, optics and vacuum by way of design,
expert advice, consultancy and training of manpower in vacuum
technology and optics/laser technology etc, required for the project.
Manpower recruited for the vacuum and laser/optics activities of IndIGO
project will be trained at RRCAT by way of participation in the various
ongoing developmental projects in the respective fields. These trained
manpower can then contribute to the IndIGO project as the facility gets
built. This mode of participation in IndIGO would lead to valuable
contributions to the project without affecting the ongoing projects at
RRCAT and also ensure that sufficient trained manpower is available
during installation and commissioning phase to run the project in a
sustainable manner.
Statement : P.K. Kaw, Director, IPR
The case for LIGO-India is very compelling. Gravitational astronomy is at the threshold
of its birth and is likely to emerge, in the coming few decades , as a totally new
window for the exploration of our Universe. Discoveries in this new field are likely
to revolutionize our understanding of the Universe and will lead to many Nobel Prizes.
We are getting an opportunity to leapfrog and participate as equal partners in this

LIGO-India vs. Indian-IGO ?
Primary advantage: LIGO-India Provides cutting edge instrumentation &
technology to jump start GW detection and astronomy.
Would require at least a decade of focused & sustained technology developments
in Indian laboratories and industry
•
180 W Nd:YAG: 5 years;
– Operation and maintenance should benefit further development in narrow line width lasers.
– Applications in high resolution spectroscopy,
– precision interferometry and metrology.
• Input conditioning optics..Expensive..No Indian manufacturer with such specs
• Seismic isolation (BCE,HAM) .. Minimum 2 of years of expt and R&D.
– Experience in setting up and maintaining these systems  know how for
isolation in critical experiments such as in optical metrology,
AFM/Microscopy, gravity experiments etc.
• 10 interferometer core optics.. manufacturing optics of this quality and
develop required metrology facility : At least 5 to 7 years of
dedicated R&D work in optical polishing, figuring and metrology.
• Five quadruple stage large optics suspensions systems.. 3-4 years of
development.. Not trivial to implement.
– Benefit other physics experiments working at the quantum limit of noise.

* Recently returned to faculty positions at premier Indian institutions (6)
– Gopakumar (Jena TIFR) and Arun (VirgoCMI) : PN modeling, dynamics of CB,
Ap and cosmological implications of parameter estimation
– Rajesh Nayak (UTB  IISER K) , Archana Pai (AEI  IISER T), Anand Sengupta
(LIGO, Caltech Delhi), Sanjit Mitra (JPL  IUCAA ): Extensive experience on
single and multi-detector detection, hierarchical techniques, noise characterisation
schemes, veto techniques for GW transients, bursts, continuous and stochastic
sources, radiometric methods, …
– P. Ajith (Caltech, LIGO/TAPIR  ? ) ……
– Sukanta Bose (Faculty UW, USA  ?)
Strong Indian presence in GW Astronomy with Global detector network 
broad international collaboration is the norm  relatively easy to get
people back.
•
Close interactions with Rana Adhikari (Caltech), B.S. Sathyaprakash (Cardiff), Sukanta
Bose ( WU, Pullman)  India ?, Soumya Mohanty (UTB), Badri Krishnan ( AEI) …
