Abstract:
Nd:Ca10K (VO4)7 crystal that polycrystalline material was synthesized by solid-phase reaction were grown by the Czochralski technique with excellent optical quality, and the dimensions were about 20 mm × 20 mm. The effective segregation coefficients of Nd3+ and K+ ions in the crystal were measured as 1.25 and 0.73, respectively. The thermal expansion coefficients and hardness of Nd:Ca10K (VO4)7 crystal were also measured. The polarized absorption and fluorescence spectra were analyzed based on Judd-Ofelt theory, which exhibits that the π-polarized absorption and stimulated emission cross sections are 5.06 × 10-20 cm2 with an FWHM 11 nm at 810 nm and 1.72 × 10-19 cm2 at 1069 nm, respectively. In addition, the fluorescence concentration quenching of Nd3+ in Nd:Ca10K (VO4)7 crystal is weak. All the results indicate that Nd:Ca10K (VO4)7 crystal may be a candidate for the microchip laser material.
