Comparative study of flux growth from molybdate and tungstane based flux systems and laser related spectroscopic properties of (Er,Yb):LuAl3(BO3)4 crystalsтезисы доклада
Аннотация:Phase relationships in the Er:YbxLu1-xAl3(BO3)4-K2Mo3O10-B2O3-(Lu,Er,Yb)2O3 (x=0-0.2, Er-1at.%) system have been studied in the temperature range from 1150 to 900оС. Multicomponent Li2WO4––B2O3 and K2Mo3O10 - B2O3 - Lu2O3 melts were used as reasonable fluxes for high-temperature solution growth of LuAl3(BO3)4 (LuAB) single crystals. The LuAB solubility in the complex flux composition has been found at 25 wt.% with decreasing temperature in the temperature interval of 1130-900oC. (Er,Yb):LuAB single crystals were grown on dipped “point” seeds. The absorption spectra of (Er,Yb):LuAB crystals were measured at room temperature. The emission spectrum and lifetime of the 4I13/2 energy level were determined.
