Abstract :
Summary form only given. Sr/sub 2/Be/sub 2/B/sub 2/O/sub 7/ (SBBO) is crystallized in space group P6~c2, with the cell dimensions a=4.683(3) /spl Aring/, c=15.311(7) /spl Aring/, and z=2. The crystal is negative uniaxial. By use of a high-temperature flux method with SrB/sub 2/O/sub 4/ as the flux, crystals of size 5/spl times/5/spl times/4 mm/sup 3/ have been grown. The growth temperature ranges from 1050-1100/spl deg/C with the melt point (1146/spl plusmn/2/spl deg/C) very near to the upper end. The crystal is transparent from 160-3780 nm. According to the D/sub 3h/ point group, there is one second harmonic generation (SHG) coefficient d/sub 22/ that was determined as 1.52 pm/V by use of the phase-matching method. This measured value is in agreement with the theoretical evaluation value of 1.44 pm/V.
