Abstract

In optical communications and the laser industry, modulating the polarization of light requires crystals with both large birefringence and a wide transparent range. A good candidate for a deep-UV birefringent crystal is ${\mathrm{Ba}}_2\mathrm{Mg}({\mathrm{B}}_3{\mathrm{O}}_6)$ because it has a large birefringence and short UV cutoff edge. We grew ${\mathrm{Ba}}_2\mathrm{Mg}{({\mathrm{B}}_3{\mathrm{O}}_6)}_2$ crystals with sizes up to $41\mathrm{m}\mathrm{m}\times 40\mathrm{m}\mathrm{m}\times 7\mathrm{m}\mathrm{m}$ using the top-seeded solution growth method. We obtained the thermal-expansion coefficients in different directions and the thermo-optic coefficients and then designed and manufactured a Glan–Taylor type polarizer to fulfill the commercial requirements.
