Optical properties and laser performance of some Yb^3^+, Er^3^+ and Tm^3^+-doped silicates - Souriau, J.C.; Romero, R.; Borel, C.; Wyon, C.; Li, C.; Moncorge, R. (Elsevier)
This paper reports the main spectroscopic characterizations and laser experiments carried out on two new crystal hosts: the yttrium orthosilicate Y"2SiO"5 and the silicate oxyapatite SrY"4(SiO"4)"3O (hereafter noted SYS), doped with ytterbium and erbium for a 1.55 μm laser emission and with thulium for a 2 μm emission. Four new lasers have been demonstrated at 1.554 μm, 1.576 μm, 1.99 μm and 2.05 μm for respectively Yb, Er:SYS; Yb,Er:Y"2SiO"5; Tm:SYS and Tm:Y"2SiO"5. If for Yb,Er-codoped materials laser performances are still poor compared with the Yb,Er phosphate glass, the Tm-doped materials exhibit laser performances similar to the Tm: YAG and look very promising.
