Frequency doubling optical components for the Nova laser system are made from single-crystal potassium dihydrogen phosphate (KDP). While developing a manufacturing process for these components, we found that single-point diamond turning could be used to directly produce finished parts with no need for additional surface polishing. A surface roughness of better than 8-A rms and 36-A P-V was measured on a test sample generated with certain machine and tool parameters. Further improvement in surface finish may be possible by employing refined diamond turning procedures and equipment.
用于诺瓦激光系统的倍频光学元件由磷酸二氢钾单晶（KDP）制成。在开发这些元件的制造工艺时，我们发现单点金刚石车削可用于直接生产成品零件，无需额外的表面抛光。在用特定的机床和刀具参数生成的测试样品上，测得表面粗糙度均方根值优于8埃，峰谷值优于36埃。通过采用改进的金刚石车削工艺和设备，表面光洁度可能会进一步提高。
