Abstract
A recipe is given for the polishing of precise surfaces on crystals of bismuth silicate (BSO) and bismuth germanate (BGO). Using this recipe, crystals having surface figure better than 1/10 wave, roughness of 20-50 Å rms, and laser quality parallelism (10 arcsec or better) were obtained with about 1-2 hours effort.
