摘　　要：LaMgAl_(11)O_(19)∶Ti(LMA∶Ti)是一种很有希望的可调谐激光晶体。本文报导了不同掺杂浓度的 LMA∶Ti 晶体的荧光光谱和激发光谱。测试结果表明,荧光强度随着掺钛浓度的提高而增强。本文还报道了 LMA∶Ti晶体的电子顺磁共振研究结果。LaMgAl_(11)O_(19):Ti(LMA:Ti) single crystal is very promisingfor turnable laser application.It is reported that both the fluorescenceand the excitation spectra in these crystals with various concentrations of ti-tanium were measured.It is indicated that the fluerescence intensity incre-ase with the increase of concentrations of Titanium in crystals.The EPRspectra in LMA:Ti crystals were also reported.
