Spectral hole lifetimes and spin population relaxation dynamics in neodymium-doped yttrium orthosilicate
Spectral hole lifetimes and spin population relaxation dynamics in neodymium-doped yttrium orthosilicate
We present a detailed study of the lifetime of optical spectral holes due to population storage in Zeeman sublevels of Nd$^{3+}$:Y$_2$SiO$_5$. The lifetime is measured as a function of magnetic field strength and orientation, temperature and Nd$^{3+}$ doping concentration. At the lowest temperature of 3 K we find a general …
