| Popis: | This paper reports the main spectroscopic characterizations and laser experiments carried out on two new crystal hosts: the yttrium orthosilicate Y 2 SiO 5 and the silicate oxyapatite SrY 4 (SiO 4 ) 3 O (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 2 SiO 5 ; Tm:SYS and Tm:Y 2 SiO 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. |
