Er,Yb:YAB Crystals, 12% Yb/1.6% Er, AR Coating, 2 mm Length
Er3+, Yb3+ co-doped yttrium aluminum borate crystals are an alternative to the commonly used Er,Yb:phosphate glass as an "eye-safe" active medium for lasers with high average output power in CW and pulsed modes. It is characterized by thermal conductivities of 7.7 Wm-1K-1 and 6 Wm-1K along the a and c axes, respectively -1.
