| 英文摘要 | A disordered Tm3+-doped Ca(GdxY1-x)Al3O7 hybrid melilite crystal (Tm:CGYAM) was successfully grown by using the optical floating zone method, and its structure and spectroscopic properties were studied thoroughly. Structure analysis shows that the Tm:CGYAM crystallizes in tetragonal system. The maximum phonon energy of Tm:CGYAM crystal is estimated to be 765.8 cm(-1). Absorption spectrum shows that the absorption cross-section of the Tm:CGYAM crystal is 0.44 x10(-20) cm(2) at 788.5 nm, with a FWHM of 34.5 nm. The radiative lifetime of Tm3+:F-3(4)-> H-3(6) transition in Tm:CGYAM crystal is calculated to be 5.35 ms by J-O analysis. The emission cross-sections are 0.321x10(-20) cm(2) at 1785 nm and 0.324x10(-20) cm(2) at 1945 nm. The FWHM of Tm3+:F-3(4)-> H-3(6) transition emission band reaches 280 nm. By fitting the fluorescence decay curve, the fluorescence lifetime of Tm3+:F-3(4) level is estimated as 4.55 ms. The gain cross-section of Tm:CGYAM crystal achieves positive in the range of 1771-2200 nm once the population inversion level reaches 10 %. All the experimental results support the Tm:CGYAM crystal can be a promising candidate material for solid state tunable or ultrashort pulse laser application. |
