QIP course on Optics of Gravitational wave detectors

The five day school on Optics of Gravitational Wave Detectors provided broad introduction to experimental techniques of interferometric gravitational wave detectors such as LIGO.

The course includes tutorials on fundamentals of optics and related areas required for an understanding of GW detectors.

The course is supported by hands-on lab session and demonstration experiments which reinforce the theoretical concepts developed in the course. The course also introduces optics related software Finesse and COMSOL.
