WebThe linear thermal expansion coefficient is the ratio change in length per degree temperature to length. Linear thermal expansion for some common metals: Metal … WebAbstract. The thermal expansion coefficient and d n /d T are measured by interferometry techniques in undoped YAG below 300 K. The thermal expansion coefficient at 125 K is measured to be 2.70 × 10 -6 K -1 and d n /d T at 633 nm is 2.5 × 10 -6 K -1, compared with 7 × 10 -6 K -1 and 9 × 10 -6 K -1 for these quantities at 300 K.
