“…During the past decade, triple-molybdates with similar structures, such as KBaGd(MoO 4 ) 3 , have also been proved to be potential candidates for laser host crystals with different output wavelengths ranging from the visible to midinfrared region with different rare-earth ions doped. [22][23][24][25][26][27] Besides, crystals in this family were also observed to have large third-order nonlinear susceptibility for stimulated Raman scattering (SRS) and have been demonstrated as efficient Raman shifters, examples can be seen in molybdates, like SrMoO 4 , 28 CaMoO 4 , 28 and PbMoO 4 , 28,29 and tungstates, like BaWO 4 , [30][31][32][33] SrWO 4 , 34 and KGd(WO 4 ) 2 . [35][36][37][38][39][40][41] Combining both the outstanding performances as laser host and Raman laser materials, rare-earth doped scheelite crystals can be used for generating self-stimulated Raman lasers.…”
