采用热锻工艺,可得到用于红外激光窗口的致密多晶KCl,它基本上不改变原单晶的光学特性,机械强度取决于热锻工艺参数。该材料用作激光窗口,能避免单晶中存在解理。 Using hot forging process, dense polycrystalline KCl for infrared laser window can be obtained, which basically does not change the optical properties of the original single crystal, the mechanical strength depends on the hot forging process parameters. This material is used as a laser window to prevent the cleavage in the single crystal.
