Paper Abstract

Single crystals of Ti:LaMgA111O19 (Ti:LMAO) up to 20 mm length have been obtained from unseeded ingots grown by the Heat Exchanger Method (HEMTM). The ingots were grown under reducing atmosphere in order to minimize formation of Ti4+. Strong fluorescence centered at 780 nm with a half-width ranging from 700 to 880 nm has been observed. The upper state fluorescence lifetime at room temperature was between 3.7 and 7.6 μs. The main broad-band absorption due to Ti3+ was centered at 510 nm. In addition, parasitic absorptions at 600 nm and 959 nm have been observed which may be associated with the formation of Ti2+.
