- Description:
- The main goal of this work was to characterize the spectroscopic properties (absorption, fluorescence, and lifetime) of the samarium ion in the yttrium-aluminum-garnet matrix. The Sm:YAG crystals with various samarium concentrations (1, 3, 6.4, 10, 15 and 20 at.% Sm/Y) were produced by the edge-defined, film-fed growth technique. Absorption characteristics were investigated in the spectral range of 185 nm - 3100 nm with detailed measurements in the near-infrared range of 1058 to 1125 nm. The results indicate that the specific absorption properties of the Sm:YAG crystal could be advantageously used to an absorb of parasitic fluorescence around 1064 nm (dominant emitted wavelength of Nd:YAG laser). The dependence of lifetime on the samarium ions concentration in the YAG matrix was proven. and Hlavním cílem této práce bylo experimentálně zjistit spektroskopické vlastnosti iontu samaria v matrici ytrium-aluminium-granátu. Pomocí metody EFG byly vyrobeny krystaly s různou koncentrací samaria (1, 3, 6,4, 10, 15, 20 at.% Sm/Y). Absorpční charakteristiky byly zkoumány ve spektrálním rozsahu 185 nm - 3100 nm, s detailním měřením v oblasti vlnové délky 1064 nm. Dále byly proměřeny emisní závislosti a doba života.
