[Poster Presentation] Investigations of population relaxation properties of hyperfine sublevels in 167Er3+ ions doped in a Y2SiO5 crystal
Daisuke Hashimoto, Kaoru Shimizu (NTT)
Abstract (in Japanese) (See Japanese page) 
(in English) We report our spectral hole burning experiments for hyperfine sublevels in ^{167}Er^{3+} ions doped in an Y_2SiO_5 crystal. We have identified a lambda-like three-level system in which we selected two hyperfine sublevels with a frequency difference of ~ 880 MHz as the two different ground levels. We have also measured the lifetime t_1 of the hyperfine sublevels. A temperature decrease from 4 K to 2.25 K promoted the value of t_1 from $12.8 pm 5.4 ms$ to $37.3 pm 7.3 ms$. We also revealed the temperature dependence of 1/t_1 as T^n (n ~ 3).
