SPECTROSCOPIC AND LASER PROPERTIES OF DIFFERENT MATERIALS DOPED WITH Pr~(3+) IONS

摘要

Examined praseodymium doped crystals with 1 at.% of Pr~(3+) ions for Y_3Al_5O_(12) (YAG), SrLaGa_3O_7 (SLGO) hosts and 3 at.% of Pr~(3+) ions for YAlO_3 (YAP) 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+):YAG, Pr~(3+):SLGO and Pr~(3+):YAP crystals have been measured. A free-running laser emission of λ = 0.744 μm for Pr: YAG and λ= 0.729 μm for Pr:SLGO for two different transmissions of output mirrors has been obtained.
