Abstract

B-BaB204 has recently been demonstrated as a promising material for both SHG and OPO applications, particularly in the UV region. We have successfully grown 0-BaB204 in a novel flux composition consisting of NaCl and Na20. Crystal growth rate was very fast in a pure NaC1 flux with well developed facets. Na20 was added as a retardant to slow down both the growth rate and spurious nucleation. The crystal habit also changed from long-prismatic shape to more equant semispherical. As the Na20 concentration increased, the crystal clarity was also reduced because of more severe flux inclusion. We believed that this was due to the contamination of carbonate in the flux since Na2CO3 was used as a pre-cursor for Na20.
