Spectral properties of Yb3+ ions in Lu3ScAl4O12 single crystal

Growth, thermal and polarized spectral properties of Nd3+-doped Li3Ba2Gd3(MoO4)8 crystal

“…Therefore, considerable attention has been devoted to the search for new more efficient materials for pumping [1][2][3][4][5][6][7][8][9][10]. Among the reported crystals, some molybdate crystals with disordered structure have generated a great deal of interest due to their intriguing properties such as high damage threshold, wide absorption band and high quantum efficiency which made them promising materials for solid-state laser gain media [11][12][13][14][15][16].…”

Growth, Thermal, and Spectroscopic Properties of YbBa3(PO4)3 Single Crystal: A New Stoichiometric Lasing Material

“…With the fast development of high-performance diode-pumped solid-state lasers with emissions centered at wavelengths near 1000 nm, significant interests have been followed with ytterbium-doped laser materials, which can be used as efficient pump sources for Yb 3+ ions. − Compared with neodymium lasers, ytterbium lasers have distinct merits such as a lack of excited-state absorption, luminescence quenching, and up-conversation and negligible nonradiative decay between the only two states in its simple electronic structure, the 2 F 7/2 ground state and the 2 F 5/2 excited state. − Furthermore, the broad absorption and emission bands allow for easy diode pumping, near-infrared tunability, and the generation of ultrashort pulses . Considering these features, Yb 3+ ion is a promising option for lasing in the near-infrared region and can also be used to sensitize other ions such as rare earth and transition metal ions. − More significantly, Yb laser crystals are highly suitable for microchip laser (or thin disk) applications.…”

Site occupation and solubility limit of Sc in Lu3Al5O12

“…Sc-containing rare-earth-doped LuAG crystals are known as laser and scintillator materials (Lu 3 Sc 2 Al 3 O 12 with Nd 3 þ and Yb 3 þ ions [3], Lu 3 ScAl 4 O 12 :Yb 3 þ [4]), (Lu 3 Al 5 À y Sc y O 12 [5]). Neither the actual compositions nor the site occupancies by constituent ions in crystals [3,4] have been identified.…”

“…Neither the actual compositions nor the site occupancies by constituent ions in crystals [3,4] have been identified. The single crystals described in [5] were of high quality when grown from melts with yr0.5, while at higher y heterogenic regions were present; the amount of Sc incorporated into the crystals was 65-80% in respect to that in initial melts.…”
