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 Ba2 MgB3 O6 because it has a large birefringence and short UV cutoff edge. We grew Ba2 MgB3 O6 2 crystals with sizes up to 41 mm × 40 mm × 7 mm 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. © 2015 Optical Society of America OCIS codes: (160.4670) Optical materials; (230.5440) Polarization-selective devices; (260.1440) Birefringence; (230.5480) Prisms. http://dx.doi.org/10.1364/AO.54.009949
1. INTRODUCTION Polarizers, optical isolators, circulators, and beam displacers that have wide applications in scientific instrumentation, optical communications, and the laser industry need crystals with both large birefringence and a wide transparent range [1]. A crystal polarizer with a high transmittance down to a deepultraviolet wavelength (deep-UV,
