Growth, crystal structure and spectrum of a novel rare-earth orthophosphate crystal: Yb:LuPO sub(4)

Yb: LuPO sub(4) crystals with the size up to 620.5mm super(3) were grown by the flux growth process using lead pyrophosphate Pb sub(2)P sub(2)O sub(7) as the high-temperature solvent. The crystal structure of Yb: LuPO sub(4) crystals at room temperature was refined by using single crystal X-ray diffraction data. Crystal structure analysis showed that Yb: LuPO sub(4) crystals possessed the tetragonal xenotime structure. The polarized absorption spectra of Yb: LuPO sub(4) were tested at room temperature. The results showed that the absorption spectral region of Yb: LuPO sub(4) crystal was well matched for pumping with readily available diode lasers.
