Abstract
⺠An Er3+ doped (Gd0.7Y0.3)2SiO5 single crystal is grown by using the Czochralski technique. ⺠Er3+:G0.7Y0.3SO crystal has a similar structure to that of GSO, which is consistent with the space group P21/c and has lattice parameters of a = 9.12 Ǻ, b = 7.04 Ǻ, c = 6.77 Ǻ, β = 107.86Ì. ⺠Er3+:G0.7Y0.3SO crystal has larger absorption line width at 1529 nm (FWHM â¼6 nm) than Er3+:YAG (â¼1.9 nm@1532 nm). ⺠The stimulated emission cross-section at 1531 nm with a value of 0.95 Ã 10â20 cm2 is higher than that reported for the Er3+:YAG crystal (Ïem = 0.75 Ã 10â20 cm2 at 1617 nm). ⺠Er3+:G0.7Y0.3SO crystal can be considered as a promising laser material operating at around 1.5 μm.
