Spectroscopic and Laser Properties of Different Materials Doped with Pr$\text{}^{3+}$ Ions

Examined praseodymium doped crystals with 1 at.% of Pr$\text{}^{3+}$ ions for Y$\text{}_{3}$Al$\text{}_{5}$O$\text{}_{12}$ (YAG), SrLaGa$\text{}_{3}$O$\text{}_{7}$ (SLGO) hosts and 3 at.% of Pr$\text{}^{3+}$ ions for YAlO$\text{}_{3}$ (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$\text{}^{3+}$:YAG, Pr$\text{}^{3+}$:SLGO and Pr$\text{}^{3+}$: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.
