Investigating the structure-sensitive factors relevant to cryogenic laser operation of Yb3+ ions in oxide crystals

Optical absorption and luminescence spectra of Yb3+ ions in Gd3(Al0.5Ga0.5)5O12, (Lu0.3Gd0.7)2SiO5 and YAl3(BO3)4 hosts crystals were examined as a function of temperature between 80 and 300 K. The analysis of obtained data provided detailed information on the thermally induced change of intensities...

Description
Summary:Optical absorption and luminescence spectra of Yb3+ ions in Gd3(Al0.5Ga0.5)5O12, (Lu0.3Gd0.7)2SiO5 and YAl3(BO3)4 hosts crystals were examined as a function of temperature between 80 and 300 K. The analysis of obtained data provided detailed information on the thermally induced change of intensities, wavelengths and bandwidths of Yb3+ transitions that governs the temperature dependence of absorption and emission cross section spectra. This information, combined with structural peculiarities of the systems studied made it possible to propose generalizations regarding the importance of the structural disorder in the Yb3+-doped laser crystals operating at cryogenic temperatures. •Examining the structure-sensitive factors relevant to Yb3+ cryogenic laser operation.•Importance of the structural disorder in the different ytterbium-doped optical systems.•Thermally-induced changes of Yb3+ involved spectroscopic qualities in GAGG, LGSO and YAB crystals.•Relevant NIR optical qualities of studied systems as function of temperature 80–300 K.
