Energy Transfer and Lasirrg of Tin-Doped Double Fluoride Crystals.

Crystal growth and spectroscopic investigations of Tm3+ ions doped 5NaF-9YF3 fluoride single crystals

“…The calculated transition probabilities and corresponding radiative lifetimes were then deduced and are given in table 2. The values found are of the same order of magnitude as those found by other fluoride hosts [17][18][19]. The principal laser transitions are those starting from the 3 F 4 , 3 H 5 , 3 H 4 , 1 G 4 and 1 D 2 multiplets towards the fundamental final level 3 H 6 .…”
