Temperature-dependent mechanical losses of Eu${}^{3+}$:Y${}_2$SiO${}_5$ for spectral hole burning laser stabilization

Nico Wagner, Johannes Dickmann, Bess Fang +2

We investigate the mechanical loss characteristics of Eu${}^{3+}$:Y${}_2$SiO${}_5$$\unicode{x2013}$a promising candidate for ultra-low-noise frequency stabilization through the spectral…
