چکیده انگلیسی
Spectroscopic features and laser performance of a novel thulium-doped scandium yttrium silicate crystal Tm3+:ScYSiO5 (Tm:SYSO) are presented. The experimental lifetime of luminescence related to the 3F4 - 3H6 laser transition of Tm3+ amounts to 1.1Â ms, which is smaller by a factor of three than the calculated radiative lifetime value due to the contribution of nonradiative relaxation. As a consequence of the internal disordered structure of the SYSO host crystal, the luminescence bands of 3F4 - 3H6 and 3H4 - 3H6 show significant inhomogeneous spectral broadening as compared with that of SSO. The laser performances were evaluated in an end-pumped cavity using a CW semiconductor laser as a pump source. In a free run regime, the Tm:SYSO laser delivered a maximum output power of 580Â mWÂ at 2022Â nm, corresponding to a slope efficiency of 17.4%. With a birefringent quartz plate inserted into laser cavity, the laser output wavelength was continuously tuned from 1950Â nm to 2057Â nm and dual wavelength operations at 2011Â nm and 2020Â nm, 1987Â nm and 2045Â nm, 2022Â nm and 2044Â nm were observed.
