| Abstract: | (Er,Yb):YAl3(BO3)4 single crystals of optical quality, up to 15 × 10 × 10 mm3 in size, have been grown from a (Er0.023Yb0.116Y0.862)Al3(BO3)4 solution in a Y2O3-B2O3-K2Mo3O10 melt. The initial borate concentration was 17 wt %, and the flux cooling rate increased from 0.08 to 0.12°C/h in the range 1060–1000°C. The physical properties of the single crystals grown are good enough that they can be used as laser elements in systems with diode pumping and radiation near 1.5 μm. |
