Spectral properties of Tm3+-doped LiLa(MoO4)2 crystal

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

“…The large value of˝2 mainly comes from the high absorption coefficient of the 4 I 9/2 → 4 G 5/2 + 2 G 7/2 hypersensitive transition around 585 nm [29,30]. This behavior has also been observed in some other molybdate crystals [14,15].…”

“…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 spectral properties of Tm 3+ , Ho 3+ co-doped NaGd(MoO 4 ) 2 Crystal

“…Tungstate crystals and molybdate crystals with formula MRe(TO 4 ) 2 (M, Re stands for alkaline and rare earth metals, respectively; T stand for Mo or W) were reported as promising host materials for solid-state laser [9][10][11][12]. This kind of crystals usually has similar scheelite CaWO 4 structure.…”

Crystal Growth and Spectroscopic Investigations of Tm3+:Li3Ba2Gd3(MoO4)8 Crystal

“…For all polarizations, the peak absorption cross-sections are located at 796 nm and the values are 4.08, 2.59, and 3.55 × 10 −20 cm 2 for E// a ′, E// b ′, and E// c ′, respectively. The full width at half the maximum (FWHM) of the 796 nm absorption peaks are 9, 11, and 8 nm for E// a ′, E// b ′, and E// c ′, respectively, which are close to those of other disordered molybdate crystals, such as Tm 3+ :LiLa(MoO 4 ) 2 (8 nm for σ polarization) [6], Tm 3+ :LiGd(MoO 4 ) 2 (8 nm for σ polarization) [8], and Tm 3+ :Ba 2 Gd 4 (MoO 4 ) 4 (7 nm for E//X and 8 nm for E//Y) [7], but much larger than those of ordered Tm 3+ :YAG (4 nm) [1], Tm 3+ :YVO 4 (5 nm for π polarization) [2], and Tm 3+ :KY(WO 4 ) 2 (5.4 nm for E//N m ) crystals [3]. Such a broad bandwidth indicates an inhomogeneous broadening behavior of Tm 3+ :Li 3 Ba 2 Gd 3 (MoO 4 ) 8 crystal and make the crystal very suitable for diode pumping, as the thermal stabilization of pumping source is not so critical in this case.…”
