| Abstract: | Recent demonstration of the wavelength tunable Ti3+:Al2O3 laser has led to increased interest in the growth and spectroscopic characters of Ti3+ Al2O3 crystal. The characteristics of crystal depend on the growth method. Two key properties of these crystals are the concentration and optical absorption cross section of the Ti3+ ions. The single crystal having high concentration of Ti3+(0.3 wt%)and good optical quality,was grown with IFUS method(Induction Field Up-Shift Method). The absorption, polarized fluorescence spectra and lifetime were masured at 300K.Analysis of the fluorescence spectra of Ti3+ ions in Al2O3 is made for the temperature ranged for 15K to 290K.The temperature dependence of fluorescence spectra of Ti3+-doped sappire is shown in Fig.6. |
