ULTRA-BROADBAND LASER GLASSES FOR SHORT-PULSE LASERS WITH HIGH PEAK CAPACITY

摘要

FIELD: chemistry.;SUBSTANCE: phosphate glass contains the following components, mol. %: P₂O₅ 50.00-70.00; B₂O₃ 2.00-10.00; Al₂O₃ 1.00-5.00; SiO₂ 1.00-5.00; Nd₂O₃ 0.10-5.00; Yb₂O₃ 0.10-35.00; La₂O₃ 0.00-20.00; Er₂O₃ 0.00-5.00; CeO₂ 0.00-20.00, where the ratio of Yb₂O₃ to Nd₂O₃ is 1-25 or 0.100-0.333.;EFFECT: increasing the width of the emission band of rare-earth ions used as generating ions in active media of solid-state lasers on glass, especially in phosphate-based glass compositions.;24 cl, 4 dwg, 6 tbl
