Some important results recently achieved with in-house grown high-quality, high-performance Hg2Cl2 and PbBr2 are described. Using an optimized crystal growth technique we have grown Hg2Cl2 crystals that show a significantly reduced acoustic attenuation from 13.4 to 8 dB/microsecond(s) -GHz2. These crystals allow the development of Hg2Cl2 Bragg cells with TBWP figures in the 5,100 - 6,900 range, frequency operation as high as TeO2 and resolution about 123% higher than TeO2 for practically similar crystal lengths. We have also grown for the first time long, high-quality PbBr2 crystals which exhibit a large figure of merit (M2 equals 550) with a modest attenuation figure of 12 dB/microsecond(s) -GHz2. This material may be the choice for devices where large diffraction efficiencies are needed.
