SYNTHETIC DIAMOND OPTICAL ELEMENTS

An optical element comprising a window formed of synthetic diamond material and an optical surface pattern formed directly in a surface of the synthetic diamond material. The window of synthetic diamond material is in the form of a wedged diamond window with non-parallel major surfaces defining a wedge angle in a range (1) arcminute to 10D and the optical surface pattern is formed directly in oneor both of the non-parallel major surfaces. There is also described a laser system comprising the optical element and a laser having a coherence length, wherein the coherence length of the laser is greater than twice a thickness of the wedged diamond window at its thickest point. 一种光学元件，包括由合成金刚石材料形成的窗口和直接形成在合成金刚石材料表面中的光学表面图案。合成金刚石材料的窗口是楔形金刚石窗口的形式，其中非平行主表面限定在1弧分至10°范围内的楔角，并且光学表面图案直接形成在一个或两个非平行中主要表面。还描述了一种激光系统，其包括光学元件和具有相干长度的激光器，其中激光器的相干长度大于楔形金刚石窗口在其最厚点处的厚度的两倍。
