Abstract
The thermal expansion coefficient and dn/dT are measured by interferometry techniques in undoped YAG below 300 K. The thermal expansion coefficient at 125 K is measured to be 2.70 x 10(-6) K(-1) and dn/dT at 633 nm is 2.5 x 10(-6) K(-1), compared with 7 x 10(-6) K(-1) and 9 x 10(-6) K(-1) for these quantities at 300 K.Entities:
