specific Embodiment approach 1
[0042] Specific implementation mode one: as Figure 1 to Figure 15 As shown, the implementation process of the micro-milling repair process method for laser damage on the surface of the large-diameter KDP crystal element described in this embodiment is:
[0043] Step 1. Design a suitable laser damage repair profile according to the laser damage degree on the KDP crystal surface and the shape characteristics of the damage point, and establish the geometric model of the repair point according to the control equation of the repair profile;
[0044] The laser damage repair profile described in step 1 mainly includes three forms: Gaussian, hemispherical and ellipsoidal. The repair profiles of these three forms are designed according to the morphology, size and distribution of laser damage points on the KDP crystal surface , for repairing the damaged surface with large damage area and small depth (ablation form), large damage point aspect ratio (pit, crack, etc.), and damage point l...
