Pr3+ doped YAG and SLGO laser rods

摘要

Abstract: Examined praseodymium doped crystals with 1 at.% of Pr$+3$PLU$/ ions for YAG and SrLaGa$-3$/O$-7$/ (SLGO) hosts were produced using Czochralski method. The luminescence for the range of 200 - 800 nm and absorption spectra for a wide range of 200 - 6000 nm, for Pr$+3$PLU$/:YAG and Pr$+3$PLU$/:SLGO crystals have been measured. It was stated that for praseodymium doped YAG and SLGO crystals, the strongest peaks of luminescence occur at 0.489 and 0.502 $mu@m and the strongest peaks of absorption occur at 0.44 - 0.5 and 0.58 - 0.62 $mu@m bands. A free-running laser emission of $lambda $EQ 0.62 $mu@m radiation for both types of crystals Pr:YAG and Pr:SLGO for two different transmissions of output mirrors have been obtained.!6
