India is going to house the third LIGO detector, at a site in Nanded, Maharashtra. Indian Institute of Technology Madras is one of the leading experimental groups, working on different aspects of research and development for LIGO-India
LIGO observatories today use highly coherent laser source at wavelength 1 µm at high power levels. Among other significant changes, advanced LIGO Voyager proposes to reduce two-photon absorption in silicon mirrors by replacing the 1 µm laser source with a 2µm laser. Such LIGO-class lasers are not yet available in 2µm wavelength. This project aims to minimize the phase noise of an available semiconductor laser at 2µm, characterize the same and design and demonstrate high power narrow line laser.
