Examined praseodymium doped crystals with 1 at.% of Pr^{3+} ions for Y_{3}Al_{5}O_{12} (YAG), SrLaGa_{3}O_{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.

Emission and absorption spectra, lifetimes, and branching ratios in the blue spectral region have been experimentally determined for numerous oxide, fluoride and phosphate materials doped with Pr^{3+} ions. The emission cross-sections have been evaluated using the principle of reciprocity. A theoretical model allowing a prediction of the blue lasing characteristics of the praseodymium activated waveguide structures has been developed and employed to the investigated materials.

Optical features (absorption and luminescence spectra) for Er^{3+} doped yttrium-aluminium garnet (YAG), yttrium orthoaluminate (YAP) and LiNbO3 crystals as well as their changes after UV and gamma irradiations are presented. Possibility of gamma-induced sensibilization process in Er^{3+} doped crystals is discussed. Positive result for non-pre-annealed gamma-irradiated rods of Er^{3+}:YAG crystal was stated.

The spectroscopic properties of trivalent dysprosium (Dy^{3+}) doped LiNbO_{3} crystals have been investigated at various temperatures. Absorption, emission, excitation and lifetime measurements have been performed and discussed in the framework of Judd-Ofelt approach. The stimulated emission cross sections of the strongest transitions of Dy ^{3+} ion have been estimated. A stimulated emission has been demonstrated in the near infrared.
