Keywords:Temperature coefficient of refractive index, YAG

We investigated the temperature coefficient of refracive index in Y3Al5O12 (YAG) single crystal from 100 K to 493 K from the temperature dependent phase shift in fringes on the transmittance caused by internal multiple reflection inside the specimen.
