Effect of Al on the spectral and spectral-hole-burning properties of sodiumborate glasses doped with Sm2+

Temperature and pressure dependence of the homogeneous width of 7F0–5D0 electronic transition in Sm2+-doped sodium borate glass

“…The details of the sample preparation and optical properties of this glass have been reported earlier [3,4]. The sample was mounted in an ordinary T-controlled (5-300 K) liquid-helium cryostat for measurements at normal P or in a pressure cell placed inside a special T-controlled (down to 4.7 K) liquidhelium cryostat for measurements at high hydrostatic P. In that case we used our high-P low-T system [5], employing compressed gaseous or solidified helium as the P-transmitting medium.…”
