许多商业上可用的钻石血小板的双折射是在激光器中腔内热管理的背景下评估的。尽管通常认为钻石是各向同性的，但在某些样品中发现了明显的双折射，从批处理到批处理有很大的变化，在某些情况下，在单个样本中有很大的变化。尽管如此，通过旋转样品或使用低双重双发性的钻石血小板，在包含Brewster元件的激光腔中实现了低损伤操作。
The birefringence of a number of commercially-available diamond platelets is assessed in the context of their use for intracavity thermal management in lasers. Although diamond is normally thought of as isotropic, significant birefringence is found to be present in some samples, with considerable variation from batch to batch, and in some cases across an individual sample. Nonetheless, low-loss operation is achieved in a laser cavity containing a Brewster element, either by rotating the sample or by using a diamond platelet with low birefringence.
