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.
